Welcome |
Broadband 3G/4G™ Radar Installation Guide
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 fi nally easy enough for casual users – identifi es 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 1/5
th
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 diff erent:
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 diff erence 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.
