Overview

SIST EN 301 091-3 V1.1.1:2017 defines the essential technical characteristics and measurement methods for radar devices operating in the 76 GHz to 77 GHz band, specifically used in obstacle detection systems at railway/road crossings. As a harmonised European standard under Directive 2014/53/EU, it ensures radio equipment within this scope meets essential requirements for health, safety, and electromagnetic compatibility.

The standard is applicable to:

• Short Range Devices (SRD) and radar equipment for obstacle detection at railway/road crossings
• Integrated transceiver systems and discrete transmit/receiver modules
• Installations where obstacle detection is critical for transport and traffic telematics (TTT), particularly at level crossings

Key Topics

• Frequency Range and Limits

  • Specifies operation strictly within the 76 GHz to 77 GHz frequency range.
  • Enforces compliance with emission and power limits for mean and peak power values.

• Technical Requirements

  • Details both transmitter and receiver performance criteria, including:
    • Control of unwanted emissions (out-of-band and spurious)
    • Receiver immunity and handling of in-band and out-of-band signals
    • Installation height and orientation requirements for effective coverage

• Measurement and Conformance

  • Outlines measurement procedures for ensuring equipment meets the defined limits.
  • Requires installation and operational instructions from the manufacturer.

• Installation and Operation

  • Demands permanent, fixed installation near the railway/road crossing at a height between 0.3 m and 5 m.
  • Specifies equipment operation for effective obstacle detection within a defined supervision area for increased safety.

• Legal Compliance

  • Compliance with this standard demonstrates presumption of conformity with Article 3.2 of the Radio Equipment Directive (2014/53/EU).
  • References CEPT/ECC recommendations for Short Range Devices.

Applications

SIST EN 301 091-3 V1.1.1:2017 is targeted at:

• Railway and Road Level Crossings

  • Enhancing safety by detecting obstacles through radar-based systems
  • Supporting automation of warning signals, barriers, and local traffic management to prevent accidents

• Smart Transport Systems

  • Integration with broader transport and traffic telematics for real-time monitoring and control
  • Enabling infrastructure providers and operators to implement safety-critical detection and response solutions

• System Integrators and Equipment Manufacturers

  • Ensuring product compliance for market access in the EU
  • Guiding development of reliable, robust, and interoperable obstacle detection systems

• Regulatory Authorities

  • Providing a basis for market surveillance and conformity assessment of SRD and radar equipment at crossings

Related Standards

When implementing SIST EN 301 091-3 V1.1.1:2017, consider referencing these related standards for comprehensive compliance and integration:

• ETSI EN 303 396: Short Range Devices; Measurement Techniques for automotive and surveillance radar equipment
• ETSI EN 301 091-1: Ground-based vehicular radar for 76 GHz to 77 GHz
• CEPT/ECC/ERC Recommendation 70-03: Guidelines for the use of Short Range Devices
• CEPT/ERC/REC 74-01: Unwanted emissions in the spurious domain
• ETSI EG 203 336: Guide for selection of parameters for harmonised standards covering the Radio Equipment Directive

---

By conforming to SIST EN 301 091-3 V1.1.1:2017, stakeholders in the railway and transport sectors can ensure safer, compliant, and more effective deployment of radar-based obstacle detection systems at critical crossing points. This contributes directly to the reliability and safety of European transport networks.

• 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
