In 1935, The British invented and patented the first radar for aircraft defence

Blurs and distorts objects, making it difficult to interpret surroundings and navigate safely

Obscures objects closest to the boat, where visibility is most important for collision avoidance

Difficulty distinguishing targets from clutter - requires experience to safely operate

Inconvenient installation and operation

Magnetron takes several inconvenient minutes to warm up

Magnetron has a limited life, and is expensive to replace

Large cables and connectors

Power consumption is impractical for small boats and most sailboats

Radar is finally easy enough for a novice – identifies targets clearly with no ‘tune control’, as sea and rain clutter rejection is 5-10 times better than a pulse radar

The pulse propagates outwards in a direction determined by the angle of the rotating radar antenna at the time of transmission.

The radar then switches to receive mode to listen for reflections.

If the pulse reflects off an object, it will return to the receiver with a delay proportional to the distance of the object from the transmitter.

Transmits a ‘rising tone’ (Tx wave) with linear increasing frequency

The wave propagates out from the transmitter retaining the frequency it had when it was transmitted

If it reflects off an object, it will return to the receiver, still at the frequency it had when originally transmitted

Eliminates 2-3 minutes warm-up time typical of magnetron pulse radars

Conserves power; operating power drain is ~30% less than the best 2 kW radar (<1/20 in standby mode) – extremely beneficial for sailboats and smaller power boats

Extremely low power - less than 1/10th of the transmitted emissions of a mobile phone; install in any position, even on the smallest of boats

Extremely low power - less than 1/10th of the transmitted emissions of a mobile phone; install in any position, even on the smallest of boats

Super small custom 13.5 mm RJ45 connector and round 9 mm pre-connected radar cable allows simple bridge tube installations
