Lowrance Broadband 4G Radar Installation Guide - Page 6

1 Welcome Congratulations on your purchase of the latest technology available in recreational marine radar. The special features designed into this radar are: • "Revolutionary improvement in situational awareness" - provides unprecedented ability to distinguish hazards and other objects • Radar is finally easy enough for casual users - identifies targets clearly with out complicated tuning adjustments • Navigation with unparalleled resolution and clarity at close ranges, where traditional radar completely obscures targets • "Start faster, go longer" - 100% solid state design - no powerful microwave transmitter required! - provides InstantOn™ power up capability and low power consumption • Eliminate the 2-3 minute warm-up time typical of traditional radars • Conserve power with a standby drain less than one tenth of the best existing radars - especially great for sailboats and smaller power boats • No expensive magnetron replacement is ever required • "Incredibly approachable"- practically imperceptible transmit emissions are extremely safe, allowing you to mount it anywhere • Less than 1/5th the transmitted emissions of a mobile phone, can be safely mounted in proximity to passengers • Compatible with a wide range of Navico multi-function displays and heading sensors What is Broadband radar? The Navico Broadband Radar uses FMCW (Frequency Modulated Continuous Wave) radar technology. FMCW radar is different: Firstly it is solid state - i.e. the transmitter is a semiconductor device, not based on magnetron technology. Secondly, it transmits a 1ms long signal of increasing frequency, rather than a short duration pulse. Thirdly, it measures the distance to a target not by timing the returned echoes, but by measuring the difference between the current transmitted frequency and echoed frequency. Hence FMCW - Frequency Modulated Continuous Wave. The building up of the image over 360 degrees and the processing of the radar data is the same as for a magnetron radar. How does FMCW radar work?
