6 | Introduction to the Navico Broadband radar system
The difference in the currently transmitted and currently received frequencies, coupled with the
known rate of frequency increase, allows a time of flight to be calculated, from which distance is
calculated
Benefits of FMCW radar
Safer
• low energy emissions, similar to a cell phone
• more flexibility in placement on boat
• can run in anchorages and marinas
Short range performance
• Conventional radars can not see anything closer than 30 meters
• FMCW can see within a few meters of the boat
• See the objects that pose the greatest threat to your boat
Low power
• expands market to small boats and yachts
• easier install, lighter cabling
• great for yachts on ocean passage
Instant power-up
• Conventional radars take 2-3 minutes to heat up the filament: Safety – 2 minutes is a long
time if you are concerned about collision
• Convenience – switch it on and use it
