ETSI ETSI EN 301 091-3 V1.1.1 (2017-02) 8 4.2 General 4.2.1 Background information In this clause general considerations for the testing of radar applications at road crossing of railway track applications in the frequency range from 76 GHz to 77 GHz are given. The tests cover integrated transceivers and separate transmit/receive modules. 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 bandwidths, 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 meaning of EUT with scanning/steerable antenna is that the EUT TX antenna pattern is electronically or mechanically adjustable. 4.2.2 Wanted performance criteria The wanted performance criterion is that the EUT shall indicate the properties of a given target at a given distance. Since EUT considered here typically are tailored to 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. 4.2.3 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 shall apply to all EUT. 4.3.1.2 Description The description in ETSI EN 303 396 [1], clause 6.2.2 applies. 4.3.1.3 Limits The upper and lower limits of the operating frequency range shall meet the following conditions: • fH ≤ 77 GHz. • fL ≥ 76 GHz.

NOTE 2: D is the antenna scan duty factor defined in ETSI EN 303 396 [1]. As D is smaller than 1 (i.e. 100 %), the log(D) value is negative and leads to a decrease in the result.
4.3.2.4 Conformance The conformance test suite for mean power shall be as defined in clause 6.3.4 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 ETSI EN 303 396 [1], clause 4.6. 4.3.3 Peak Power 4.3.3.1 Applicability

4.2 General
4.2.1 Background information
In this clause general considerations for the testing of radar applications at road crossing of railway track applications in
the frequency range from 76 GHz to 77 GHz are given. The tests cover integrated transceivers and separate
transmit/receive modules.
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 bandwidths, 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 meaning of EUT with scanning/steerable antenna is that the EUT TX antenna pattern is electronically or
mechanically adjustable.
4.2.2 Wanted performance criteria
The wanted performance criterion is that the EUT shall indicate the properties of a given target at a given distance.
Since EUT considered here typically are tailored to 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.
4.2.3 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 shall apply to all EUT.
4.3.1.2 Description
The description in ETSI EN 303 396 [1], clause 6.2.2 applies.
4.3.1.3 Limits
The upper and lower limits of the operating frequency range shall meet the following conditions:
• f ≤ 77 GHz.
H
≥ 76 GHz.
• f
L

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 measurements uncertainty shall be as given in ETSI EN 303 396 [1], clause 4.6.
4.3.2 Mean Power
4.3.2.1 Applicability
This requirement shall apply to all EUT.
4.3.2.2 Description
The description in ETSI EN 303 396 [1], clause 6.2.5 applies.
4.3.2.3 Limits
The mean power shall not be greater than the limits in table 2.
Table 2: Mean power [i.1]
EUTs others than pulsed radar Pulsed radar
mean power (e.i.r.p.) 50 dBm 23,5 dBm
NOTE: For the purposes of this measurement, the averaging time shall be not greater than 100 ms. If the
result varies through the EUT cycle time the maximum value shall be taken as the result.

For constant pattern scanning antennas measured with the scanning inhibited (clause 4.3.5 of ETSI EN 303 396 [1]), the
mean power shall be calculated from the measured result P as shown in table 3.
MEASURED
Table 3: Mean power calculation (constant pattern scanning antenna)
EUTs others than pulsed radar Pulsed radar
Illumination time t t ≤ 100 ms t > 100 ms t ≤ 100 ms t > 100 ms

MEASURED MEASURED MEASURED MEASURED
(see note 2)
NOTE 1: t is the illumination time defined in ETSI EN 303 396 [1].
NOTE 2: D is the antenna scan duty factor defined in ETSI EN 303 396 [1]. As D is smaller than 1
(i.e. 100 %), the log(D) value is negative and leads to a decrease in the result.

4.3.2.4 Conformance
The conformance test suite for mean power shall be as defined in clause 6.3.4 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 ETSI EN 303 396 [1], clause 4.6.
4.3.3 Peak Power
4.3.3.1 Applicability
This requirement shall apply to all EUT.

In this clause all general considerations for the testing of radar applications at road crossing of railway track
applications in the frequency range from 76 GHz to 77 GHz are given. The tests covers integrated transceivers and
separate transmit/receive modules.
All operating bandwidths of the equipment (see clause 4.3.1) shall be declared by the equipment manufacturer (see
clause 4.2 of ETSI EN 303 396 [1]).
Where equipment has more than one operating bandwidths, 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.
The meaning of EUT with scanning/steerable antenna is that the EUT TX antenna pattern is electronically or
mechanically adjustable.
4.2.2 Wanted performance criteria
The wanted performance criterion is that the EUT shall indicate the properties of a given target at a given distance.
Since EUT considered here typically are tailored to specific applications, no single wanted performance criterion can be

4.2 General
4.2.1 Background information
In this clause all general considerations for the testing of radar applications at road crossing of railway track
applications in the frequency range from 76 GHz to 77 GHz are given. The tests covers integrated transceivers and
separate transmit/receive modules.
All operating bandwidths of the equipment (see clause 4.3.1) shall be declared by the equipment manufacturer (see
clause 4.2 of ETSI EN 303 396 [1]).
Where equipment has more than one operating bandwidths, 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.
The meaning of EUT with scanning/steerable antenna is that the EUT TX antenna pattern is electronically or
mechanically adjustable.
4.2.2 Wanted performance criteria
The wanted performance criterion is that the EUT shall indicate the properties of a given target at a given distance.
Since EUT considered here typically are tailored to 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.
4.2.3 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 shall apply to all EUT.
4.3.1.2 Description
The description in ETSI EN 303 396 [1], clause 6.2.2 applies.
