It is recognised that small vessels, often made of glass fibre reinforced plastic (GRP), can be poor reflectors of radar signals. In situations where radar is the prime observation tool used by ships at sea, the International Maritime Organisation considers that it is essential that small vessels, considered in this context to be those under 150 gross tonnage, be equipped with a radar reflector to enhance their radar return and thus improve their visibility to radar. ISO 8729-2:2009 specifies the minimum requirements for a radar reflector intended to enhance returns from small vessels as required by IMO Resolution MSC.164(78). It provides the specification for the construction, performance, testing, inspection and installation of such radar reflectors.
Abstract
Overview
ISO 8729-2:2009 - Ships and marine technology - Marine radar reflectors - Part 2: Active type defines minimum requirements for active radar reflectors (also known as radar target enhancers, RTE) intended to improve radar visibility of small vessels. Published to support IMO Resolution MSC.164(78), the standard addresses the construction, performance, testing, inspection and installation of active reflectors for vessels normally under 150 gross tonnage that can be poor natural radar reflectors (e.g., GRP hulls).
Key topics and technical requirements
- System architecture: receive antenna(s), amplifier(s) (covering X‑band and S‑band), and transmit antenna(s); may include a control box for on/off and status indication.
- Performance (reflecting pattern):
- Stated performance level (SPL): minimum 7.5 m RCS in X‑band (9.300–9.500 GHz) and 0.5 m RCS in S‑band (2.900–3.100 GHz).
- SPL must be maintained over at least 280° azimuth.
- No nulls wider than 10° at the SPL; spacing between nulls must be ≥ 20° (nulls
