Introduction
The present document, together with ETSI EN 303 396 [1], covers the assessment of certain types of equipment as
defined herein.
ETSI
6 Draft ETSI EN 303 360 V1.1.1 (2016-12)
1 Scope
The present document specifies technical characteristics and methods of measurements for the following type of
equipment:
• Radar equipment for obstacle detection for rotorcraft use fitted with integral antennas operating in the
frequency range from 76 GHz to 77 GHz and references CEPT/ERC/ECC Recommendation 70-03 [i.1],
Annex 5 and Commission Decision 2006/771/EC [i.2] as amended.
NOTE 1: The use of the radar equipment is limited to manned rotorcraft for which certification specifications
CS-27 [i.9] for small rotorcraft or CS-29 [i.10] for large rotorcraft apply (since pilots need to verify
visually the information directly by themselves).
• Short Range Devices (SRD) intended for the use on board rotorcrafts with the application to detect obstacles.
NOTE 2: The intention of the application is to detect obstacles to increase safety for aircrew, passengers and
persons on ground by reducing risk of collision with obstacles. It is not considered as a safety of life
application.
NOTE 3: Protection to the Radio Astronomy Service as detailed in annex B is applicable for obstacle detection
radars for rotorcraft use as described in the present document.
It covers integrated transceivers.
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 does not necessarily include all the characteristics which may be required by a user, nor does it
necessarily represent the optimum performance achievable.
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 (Commission Decision 2006/771/EC [i.2])
Permitted range of operation
Transmit 76 GHz to 77 GHz
Receive 76 GHz to 77 GHz
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 specifications
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 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
4.2.1 Background information
In this clause general considerations for the testing of radar applications for the EUT are given.
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 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 are typically 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 Technical requirements specifications
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 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
4.2.1 Background information
In this clause general considerations for the testing of radar applications for the EUT are given.
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 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 are typically 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.

Modal verbs terminology In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and "cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). "must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation. 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 303 360 V1.1.1 (2017-02) 6 1 Scope The present document specifies technical characteristics and methods of measurements for the following type of equipment: • Radar equipment for obstacle detection for rotorcraft use fitted with integral antennas operating in the frequency range from 76 GHz to 77 GHz and references CEPT/ERC/ECC Recommendation 70-03 [i.1], Annex 5 and Commission Decision 2006/771/EC [i.2] as amended. NOTE 1: The use of the radar equipment is limited to manned rotorcraft for which certification specifications CS-27 [i.9] for small rotorcraft or CS-29 [i.10] for large rotorcraft apply (since pilots need to verify visually the information directly by themselves). • Short Range Devices (SRD) intended for the use on board rotorcrafts with the application to detect obstacles. NOTE 2: The intention of the application is to detect obstacles to increase safety for aircrew, passengers and persons on ground by reducing risk of collision with obstacles. It is not considered as a safety of life application. NOTE 3: Protection to the Radio Astronomy Service as detailed in Annex B is applicable for obstacle detection radars for rotorcraft use as described in the present document. It covers integrated transceivers. 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 does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable. 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 (Commission Decision 2006/771/EC [i.2]) Permitted range of operation Transmit 76 GHz to 77 GHz Receive 76 GHz to 77 GHz
