EN 62388:2013

Maritime navigation and radiocommunication equipment and systems - Shipborne radar - Performance requirements, methods of testing and required test results

IEC 62388:2013(E) specifies the minimum operational and performance requirements, methods of testing and required test results conforming to performance standards not inferior to those adopted by the IMO in Resolution MSC.192(79). (MSC.192/2) The radar installation, in addition to meeting the general requirements as set out in resolution A.694(17) and the related standard IEC 60945, should comply with the performance standards of MSC.192(79). When a requirement of this standard is different from IEC 60945, the requirement in this standard takes precedence. This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision.

L'IEC 62388:2013 spécifie les exigences de performance et opérationnelles minimales, les méthodes d'essais et les résultats d'essais exigés conformément aux normes de performance non inférieures à celles adoptées par l'OMI dans la Résolution MSC.192(79). (MSC.192/2) Il convient que l'installation radar, en plus de satisfaire aux exigences générales indiquées dans la Résolution A.694(17) et dans la norme connexe IEC 60945, satisfasse aux exigences de performance de la MSC.192(79). Lorsqu'une exigence de la présente norme diffère de l'IEC 60945, c'est l'exigence de la présente norme qui prévaut. Cette deuxième édition annule et remplace la première édition parue en 2007. Cette édition constitue une révision technique.

Oprema in sistemi za pomorsko navigacijo in radiokomunikacije - Ladijski radar - Tehnične zahteve, metode preskušanja in zahtevani rezultati preskušanja

Ta mednarodni standard določa minimalne zahteve za delovanje in tehnične zahteve, preskusne metode in zahtevane rezultate preskusov, ki so skladni s standardi o lastnostih in niso manjvredni od tistih, ki jih je sprejela Mednarodna pomorska organizacija (IMO) v resoluciji MSC.192(79). (MSC.192/2) Namestitev radarja mora biti poleg izpolnjevanja splošnih zahtev, navedenih v resoluciji A.694(17) in s tem povezanem standardu IEC 60945, skladna s standardi o lastnostih MSC.192(79). Če se zahteva iz tega standarda razlikuje od zahteve iz standarda IEC 60945, ima prednost zahteva iz tega standarda.

Overview

EN 62388:2013 (identical to IEC 62388:2013) defines performance requirements, test methods and required test results for shipborne radar used in maritime navigation and radiocommunication. The standard specifies minimum operational and performance criteria that are at least as stringent as those adopted by the IMO in Resolution MSC.192(79). Where this standard differs from IEC 60945, its requirements take precedence. This edition supersedes EN 62388:2008 and introduces a technical revision covering transmission, display presentation, AIS handling, chart-radar functionality and alert management.

Key technical topics and requirements

• Radar performance and testing: Defines measurement conditions, test sites (including over-sea tests), target simulation and documentation of radar performance results.
• Transmission and interference: Frequency and unwanted emissions requirements (mask tightened from 20 dB/decade to 30 dB/decade to align with ITU), plus guidance on adjacent-band interference.
• Signal processing & anti-clutter: Requirements for gain control, sea/clutter suppression (manual and automatic), rain clutter handling, target enhancement and latency limits.
• Range, bearing and discrimination: Minimum range, range compensation, range/bearing discrimination and fundamental radar accuracy.
• Antenna performance: Vertical radiation/pitch-and-roll characteristics, horizontal pattern and side-lobe control.
• Target detection: Procedures for assessing first detection range in minimal clutter and performance in cluttered conditions.
• Display presentation & ergonomics: Simplified display requirements referencing EN 62288, new modes such as head-up stabilised, and ergonomics (default control settings).
• Integration & interfaces: AIS handling (new tests for AIS target types, repeaters and filtering), ECDIS backup (chart radar), VDR interfaces, and Bridge Alert Management alignment.
• Documentation & maintenance: Equipment familiarisation, maintenance information and update procedures.

Practical applications and who uses it

• Radar and navigation equipment manufacturers for design verification and CE/market compliance.
• Shipyards and system integrators installing shipborne radar systems and interfacing radars with ECDIS, AIS and VDR.
• Testing laboratories and certification bodies performing type approval and conformance testing against IEC/EN requirements.
• Classification societies, flag administrations and maritime regulators that assess equipment for statutory compliance with IMO performance standards.
• Ship operators and navigators seeking assurance of radar reliability, detection performance and ergonomic presentation under operational conditions.

Related standards and references

• IEC 60945 (general maritime equipment)
• IEC 62288 (display presentation)
• IEC 61162 (digital interfaces), IEC 61174 (ECDIS)
• IMO resolutions MSC.192(79), MSC.191(79), MSC.302(87) (Bridge Alert Management)
• ITU-R recommendations and IHO S-52 (ECDIS display)

SIST EN 62388 is essential for ensuring shipborne radar systems meet internationally harmonized maritime navigation performance and testing expectations.
