Radar and radar antennas for collision avoidance. Arguably, one of the surest collision avoidance technologies on board is considered to be the radar unit. And even if we at SVB actively promote class B AIS devices for use in the water sports sector and co-develop new systems, we still do not recommend going without a radar unit on board for your own safety.
Modern radar equipment comes with a variety of functions such as MARPA (Mini Automatic Radar Plotting Aid), map and AIS overlay. Some pulse compression radars feature Doppler radar technology which offers colour coded Doppler target processing.
