Introduction The present document, together with ETSI EN 303 396 [1], covers the assessment of certain types of equipment as defined herein.

ETSI ETSI EN 301 091-3 V1.1.1 (2017-02) 6 1 Scope The present document specifies technical characteristics and methods of measurements for the following types of equipment: • radar equipment for obstacle detection applications in the frequency range from 76 GHz to 77 GHz at the road crossing of a railway track and references CEPT/ECC ERC Recommendation 70-03 [i.1] Annex 4; • Short Range Devices (SRD) intended for the use at road crossing of a railway track. It covers integrated transceivers and separate transmit/receive modules. The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable. 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. These radio equipment types are capable of operating in all or part of the frequency bands given in table 1. Table 1: Permitted range of operation [i.1] Permitted range of operation Transmit 76 GHz to 77 GHz Receive 76 GHz to 77 GHz

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]. SIST EN 301 091-3 V1.1.1:2017

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.

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 PMEASURED as shown in table 3. Table 3: Mean power calculation (constant pattern scanning antenna)

EUTs others than pulsed radar Pulsed radar Illumination time t (see note 1) t ≤ 100 ms t > 100 ms t ≤ 100 ms t > 100 ms mean power (e.i.r.p)

(see note 2) PMEASURED + 10 log(D) PMEASURED PMEASURED + 10 log(D) PMEASURED 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.
