In 1935, The British invented and patented the first radar for aircraft defence 6. Blurs and distorts objects, making it difficult to interpret surroundings and navigate safely 16. 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 18. © Navico Company Confidential 8 Comparison and Main bang main bang 4 kW HD pulse radar, 1/8 NM range BroadBand Radar, 1/16 NM range 19. © Navico Company Confidential 9 Comparison and Main bang main bang suppression 4 kW HD pulse radar, 1/8 NM range Broadband Radar, 1/16 NM range 20. © Navico Company Confidential 10 Close Range Performance 21. © Navico Company Confidential 11 Approximate position of boat Close Range Performance Moored boat Foot bridge 4 kW HD pulse radar Broadband Radar 22. © Navico Company Confidential 12 Superb Resolution Pile moorings Moored boat 4 kW HD Pulse Radar BroadBand Radar 23. © Navico Company Confidential 13 Seaclutter Performance Two boats, towing into the harbour 4 kW HD pulse radar, 1/2nm Sea clutter rejection 50% BroadBand Radar ¼ NM No sea clutter rejection applied 26. The pulse propagates outwards in a direction determined by the angle of the rotating radar antenna at the time of transmission. 27. The radar then switches to receive mode to listen for reflections. 28. 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. 31. The wave propagates out from the transmitter retaining the frequency it had when it was transmitted 32. If it reflects off an object, it will return to the receiver, still at the frequency it had when originally transmitted 37. 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 42. 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 46. 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 47. Super small custom 13.5 mm RJ45 connector and round 9 mm pre-connected radar cable allows simple bridge tube installations 56. © Navico Company Confidential 30 Long Range Performance Scanner height Target Object at sea level Small boat (2 m high) Big launch (6 m high) 2 metres 3.1 miles 6.3 miles 8.5 miles 3 metres 3.8 miles 7.0 miles 9.2 miles 4 metres 4.4 miles 7.5 miles 9.8 miles Maximum range for any radar under ideal circumstances: __________________________________________________________________________ So….. there is no possible way a radar on a small/medium boat can see a large launch at more than 10 miles But… It may be possible to see rain or high land features beyond 10 miles. 57. © Navico Company Confidential 31 Further Enhancement Navico’s R&D teams have developed technologies, which bring interference from other radar and onboard reflectors to a minimum or even totally eliminates them. This also means we are not depending on already patented technologies, which would have influenced the price of the radar.
