Simrad launches two small boat radars
Electronics specialist Simrad has launched two additions to its range of Halo radars that are specifically designed for smaller craft writes Dag Pike.
The HALO20+ and HALO20 radars are a pair of compact, pulse-compression units designed for smaller boats with particular application to small workboats such as harbour craft and RIBs. Both radars provide excellent detection with short-range performance, while the HALO20+ has the fastest rotation amongst all small boat radars which gives a rapid picture update making it suitable for high speed boats. The HALO20+ also has a longer detection range and can detect targets farther away than the HALO20.
With its 20-inch radome, the HALO20+ is Simrad’s smallest pulse compression radar scanner yet, delivering a full 360-degree sweep every second. Simrad says it has an industry-first 60RPM rotation at ranges up to 1.5nm and that these fast updates give operators an almost real-time view of close range activity, helping to avoid collisions and keep track of fast-moving targets.
The new radars are made for a wide range of coastal boats with the HALO20+ offering high-quality detection at both short ranges and longer ranges up to 36 miles. It is also possible to monitor two ranges at the same time in the Dual Range mode which means that it is possible to monitor distant coastlines and shipping to help navigation whilst also tracking fast boats that are operating nearby. The radars can detect targets just 6 metres away and a useful feature is beam sharpening which effectively narrows the beam width to aid the separation of targets.
For collision avoidance the HALO20+ delivers instant feedback on whether targets are moving towards or away from the vessel by means of colour coding. This coding also gives improved situational awareness and reduces the risk of a collision. For this feature the radar automatically checks the Doppler returns for every target in range, so that selection is automatic and does not require user input.
The cheaper HALO20 radar has a detection range of up to 24 miles and it has a smaller footprint and a low profile which makes it suitable for smaller boats. It can track up to 10 targets at any time.
