1 Scope

The present document specifies the technical characteristics and test methods for automotive ultra-wideband (UWB)

radar equipment fitted with integral antennas operating in the frequency range from 24,25 GHz to 26,65 GHz working

as broadband devices with at least 500 MHz bandwidth and references CEPT/ERC Recommendation 70-03 [i.1] and EC

Decision 2013/752/EU [i.2].

This equipment is intended for Transport and Traffic Telematics (TTT) applications according to ERC

Recommendation 70-03 [i.1], annex 5, such as obstacle detection, stop and go, blind spot detection, parking aid, backup

aid, precrash and other automotive applications.
Table 1 shows the frequency bands as designated to ultra-wideband (UWB) radar.
Table 1: Frequency of operation
Frequency bands / frequencies Frequency bands / frequencies
Transmit 1 24,25 GHz to 26,65 GHz UWB mode
Receive 1 24,25 GHz to 26,65 GHz UWB mode
Transmit 2 24,05 GHz to 24,25 GHz (see note) Single carrier emissions (see note)
Receive 2 24,05 GHz to 24,25 GHz (see note) Single carrier emissions (see note)

NOTE: Single carrier emissions in the SRD band from 24,05 GHz to 24,25 GHz according to the present

document may not be used on its own, but only in conjunction with UWB emissions in the 24,25 GHz to

26,65 GHz range. For 24,05 GHz to 24,25 GHz devices the present document does not apply and the

correct standard is ETSI EN 302 858 [i.11].

In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present

document and ETSI EN 303 396 [1], the provisions of the present document take precedence.

The present document covers transmitters intended to operate in a temporary frequency designation under the ECC

decision CEPT/ECC/DEC/(04)10 [i.6], the EU Commission decision 2005/50/EC [i.7] and the amendment as presented

in RSCOM11-07 [i.9].

• The operating frequency range for intentional UWB emissions has been determined from 21,65 GHz to

26,65 GHz until 30 June 2013. This is no longer covered by the present document.

• Since 30 June 2013 the operating frequency range for intentional UWB has reduced frequency band from

24,25 GHz to 26,65 GHz until 1 January 2018, with an extension for car models which have received type

st st

approval before 1 January 2018 and which can continue to be put on the market until 1 January 2022 [i.6].

This equipment is covered by the present document.

The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.3] under the

conditions identified in annex A.

4.2.1 Wanted performance criteria

The wanted performance criterion is that the EUT shall indicate the properties of a given target at a given distance.

Since EUTs considered here typically are tailored to very specific applications, no single wanted performance criterion

can be defined here.
Therefore:

• the relevant properties (e.g. presence, range, relative speed, azimuth angle) shall be declared by the

manufacturer;

• the type and RCS of the target and the distance shall be declared by the manufacturer.

4.2.2 Fixed and scanning antennas
The provisions of ETSI EN 303 396 [1], clause 4.3.5 apply.
4.3 Transmitter Conformance Requirements
4.3.1 Operating Frequency Range
4.3.1.1 Applicability
This requirement applies to all EUT.
4.3.1.2 Description
The description in ETSI EN 303 396 [1], clause 6.2.2 applies (99 % OBW).

Alternatively to the 99 % OBW definition, the procedure from clause 4.3.2.2 may be used:

• The frequency, f , at which the amplitude of the radiated spectrum is maximum is determined from the

spectrum analyser curve. The lower frequency, f , and the higher frequency, f , where the radiated spectrum

L H
density is 20 dB below maximum are recorded.

The method used to determine "operating frequency range" should be indicated in the test report.

4.3.1.3 Limits

For ultra-wideband radar equipment, the upper and lower limits of the operating frequency range shall meet the

following conditions:
• f ≤ 26,65 GHz.
• f ≥ 24,25 GHz.

In case that emissions in an ultra-wideband mode between 24,25 GHz and 26,65 GHz are present, optional single carrier

emissions are allowed with the following upper and lower limits of the operating frequency range:

• f ≤ 24,25 GHz.
• f ≥ 24,05 GHz.
4.3.1.4 Conformance

The conformance test suite for operating frequency range shall be as defined in clause 6.3.2 of ETSI EN 303 396 [1].

Conformance shall be established under normal and extreme test conditions defined in clause 4.1.

ETSI

10 ETSI EN 302 288 V2.1.1 (2017-05)

The interpretation of the results for the measurement uncertainty shall be as given in clause 4.6 of ETSI EN 303 396 [1].

4.3.2 Mean Power Spectral Density
4.3.2.1 Applicability
This requirement applies to all EUT.
4.3.2.2 Description

The description in ETSI EN 303 396 [1], clause 6.3.5 applies, except for the following item:

• Measurements of power densities below -75 dBm/MHz (e.i.r.p.) are not required.
4.3.2.3 Limits

The average power shall not be greater than the limits in table 2, in accordance to ECC Decision (04)10, Annex 2 [i.7].

Table 2: Ultra-wideband and single carrier limits for maximum
radiated average power spectral density

Signal category Frequency range Maximum radiated average power spectral density (e.i.r.p.)

in 1 MHz RBW

Single carrier emissions 24,05 GHz < f < 24,25 GHz 10 dBm (20 dB peak emissions with 10 % duty cycle)

(note)
Ultra-wideband emissions 24,25 GHz < f < 25,65 GHz -41,3 dBm / MHz
Ultra-wideband emissions 25,65 GHz < f < 26,65 GHz
-41,3 dBm - 20 × (f - 25,65 GHz) / 1 GHz dBm/MHz

NOTE: Single carrier emissions may only be present in case of intentional UWB emissions within the band 24,25 GHz

to 26,65 GHz.
4.3.2.4 Conformance

The conformance test suite for mean power spectral density shall be as defined in clause 6.3.5 of ETSI EN 303 396 [1].

Conformance shall be established under normal and extreme test conditions defined in clause 4.1.

The interpretation of the results for the measurements uncertainty shall be as given in clause 4.6 of ETSI

EN 303 396 [1].
4.3.3 Peak Power
4.3.3.1 Applicability
This requirement applies to all EUT.
4.3.3.2 Description

For ultra-wideband devices, the maximum radiated peak power density including antenna gain (e.i.r.p.) is defined as the

peak power measured in a 50 MHz resolution bandwidth (RBW), in accordance to ECC Decision (04)10, Annex 2 [i.6].

No further correction factor (PDCF) is applied to the readings measured in the 50 MHz RBW. Furthermore the video

bandwidth (VBW) shall be at least as large as the RBW for correct peak measurements.

1 Scope

The present document specifies the technical characteristics and test methods for automotive ultra-wideband (UWB)

radar equipment fitted with integral antennas operating in the frequency range from 24,25 GHz to 26,65 GHz working

as broadband devices with at least 500 MHz bandwidth and references CEPT/ERC Recommendation 70-03 [i.1] and EC

Decision 2013/752/EU [i.2].

This equipment is intended for Transport and Traffic Telematics (TTT) applications according to ERC

Recommendation 70-03 [i.1], annex 5, such as obstacle detection, stop and go, blind spot detection, parking aid, backup

aid, precrash and other automotive applications.
Table 1 shows the frequency bands as designated to ultra-wideband (UWB) radar.
Table 1: Frequency of operation
Frequency bands / frequencies Frequency bands / frequencies
Transmit 1 24,25 GHz to 26,65 GHz UWB mode
Receive 1 24,25 GHz to 26,65 GHz UWB mode
Transmit 2 24,05 GHz to 24,25 GHz (see note) Single carrier emissions (see note)
Receive 2 24,05 GHz to 24,25 GHz (see note) Single carrier emissions (see note)

NOTE: Single carrier emissions in the SRD band from 24,05 GHz to 24,25 GHz according to the present

document may not be used on its own, but only in conjunction with UWB emissions in the 24,25 GHz to

26,65 GHz range. For 24,05 GHz to 24,25 GHz devices the present document does not apply and the

correct standard is ETSI EN 302 858 [i.11].

In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present

document and ETSI EN 303 396 [1], the provisions of the present document take precedence.

The present document covers transmitters intended to operate in a temporary frequency designation under the ECC

decision CEPT/ECC/DEC/(04)10 [i.6], the EU Commission decision 2005/50/EC [i.7] and the amendment as presented

in RSCOM11-07 [i.9].

• The operating frequency range for intentional UWB emissions has been determined from 21,65 GHz to

26,65 GHz until 30 June 2013. This is no longer covered by the present document.

• Since 30 June 2013 the operating frequency range for intentional UWB has reduced frequency band from

24,25 GHz to 26,65 GHz until 1 January 2018, with an extension for car models which have received type

st st

approval before 1 January 2018 and which can continue to be put on the market until 1 January 2022 [i.6].

This equipment is covered by the present document.

The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.3] under the

conditions identified in annex A.

4 Technical requirements specification
4.1 Environmental conditions

The technical requirements of the present document apply under the environmental profile for operation of the

equipment, which shall be declared by the manufacturer. The equipment shall comply with all the technical

requirements of the present document which are identified as applicable in annex A at all times when operating within

the boundary limits of the declared operational environmental profile.

The normal and extreme test conditions are defined in clauses 4.4.3 and 4.4.4 of ETSI EN 303 396 [1].

4.2 General
4.2.0 Multiple operating bandwidths

All operating bandwidths of the equipment (see clause 4.3.1) shall be declared by the equipment manufacturer (see

clauses 4.2 and 4.3 of ETSI EN 303 396 [1]).

Where equipment has more than one operating bandwidth, a sufficient number of operating bandwidths shall be chosen

for testing so as to encompass the lower and higher limits of the operating frequency and the minimum and maximum

bandwidth.

The EUT modulation during testing should be representative of normal use of the equipment. The manufacturer shall

employ the mode of operation of the equipment which results in the highest transmitter activity consistent with the

requirement to measure the highest power transmission which would be available in operation, and should ensure that:

• transmissions occur regularly in time;
• sequences of transmissions can be repeated accurately.

For transmitters that have multi-modulation schemes incorporated, it may be necessary to test each scheme.

4.2.1 Wanted performance criteria

The wanted performance criterion is that the EUT shall indicate the properties of a given target at a given distance.

Since EUTs considered here typically are tailored to very specific applications, no single wanted performance criterion

can be defined here.
Therefore:

• the relevant properties (e.g. presence, range, relative speed, azimuth angle) shall be declared by the

manufacturer;

• the type and RCS of the target and the distance shall be declared by the manufacturer.

4.2.2 Fixed and scanning antennas
The provisions of ETSI EN 303 396 [1], clause 4.3.5 apply.
4.3 Transmitter Conformance Requirements
4.3.1 Operating Frequency Range
4.3.1.1 Applicability
This requirement applies to all EUT.
4.3.1.2 Description
The description in ETSI EN 303 396 [1], clause 6.2.2 applies (99 % OBW).

Alternatively to the 99 % OBW definition, the procedure from clause 4.3.2.2 may be used:

• The frequency, f , at which the amplitude of the radiated spectrum is maximum is determined from the

spectrum analyser curve. The lower frequency, f , and the higher frequency, f , where the radiated spectrum

L H
density is 20 dB below maximum are recorded.

The method used to determine "operating frequency range" should be indicated in the test report.

4.3.1.3 Limits

For ultra-wideband radar equipment, the upper and lower limits of the operating frequency range shall meet the

following conditions:
• f ≤ 26,65 GHz.
• f ≥ 24,25 GHz.

In case that emissions in an ultra-wideband mode between 24,25 GHz and 26,65 GHz are present, optional single carrier

emissions are allowed with the following upper and lower limits of the operating frequency range:

• f ≤ 24,25 GHz.
• f ≥ 24,05 GHz.
4.3.1.4 Conformance

The conformance test suite for operating frequency range shall be as defined in clause 6.3.2 of ETSI EN 303 396 [1].

Conformance shall be established under normal and extreme test conditions defined in clause 4.1.

The interpretation of the results for the measurement uncertainty shall be as given in clause 4.6 of ETSI EN 303 396 [1].

4.3.2 Mean Power Spectral Density
4.3.2.1 Applicability
This requirement applies to all EUT.
4.3.2.2 Description

The description in ETSI EN 303 396 [1], clause 6.3.5 applies, except for the following item:

• Measurements of power densities below -75 dBm/MHz (e.i.r.p.) are not required.
4.3.2.3 Limits

The average power shall not be greater than the limits in table 2, in accordance to ECC Decision (04)10, Annex 2 [i.7].
