概述： Simrad Broadband 4G? is the first dome radar to employ Beam Sharpening. This technology enables a new feature called Target Separation Control, which improves the Azimuth resolution, or effective antenna horizontal beam width, up to double the resolution of any 18-inch dome radar. This is the equivalent of a three and a half foot open array radar. Improved Range Performance with Noise Rejection Control
Broadband 4G? Radar uses advanced levels of Digital Signal Processing to reduce the amount of noise picked up by the radome's surroundings. Users can choose the levels of Noise Rejection via an onscreen menu and decide between LOW or HIGH rejection to customise their views (displays without Noise Rejection Control automatically default to High, in this case Target Separation will also be High).
Noise Rejection Control increases the Broadband 4G Radar range by up to 50% and also increases target detection sensitivity. 描述：Display Technical/Environmental Mounting [S,F,B] Bolts: 4x30xM8 - 304 stainless steel Operating Temperature -13° to +131°F/-25° to +55°C Diameter [mm] 488 mm 19.2 in Waterproof Standard/rating IPX6 Product Height 280 mm 11 in Product Weight 7.4 kg 16.31 lbs Other Humidity Range [rh] +95°F/+35°C, 95% RH Power Power Consumption 18W (Typ.) @ 13.8vDC Power Supply (Supply Voltage) 9 to 31.2vDC (12/24 Volt systems) Reverse polarity protection vDC Power Consumption Standby 2W(Typ.) @ 13.8vDC~ only 150ma Communications Data I/O Protocol High Speed Ethernet Transmitter Power Output 165mW nominal Transmitter Frequency X-band - 9.3 to 9.4GHz Radar Antenna Horizontal Beam Width [deg] 5.2°+/-10% (-3dB width) ° Antenna Receiver Noise Figure [dB] 6 Antenna Rotation Speed 24/36 rpm +/- 10% RPMs Antenna Vertical Beam Width 25°+/-20% (-3dB width) ° Beam Width 2.6° Radar Wind Resistance 51 m/sec (Max:100 Knots) Radar Warm Up Time [minutes] 0
