A Short History of Radar
In 1917, Nikola Tesla first established the principles for primitiveradar units
In 1935, The British invented and patented the first radar foraircraft defense
In 1950, Decca introduced the first marine pulse radar utilizing amagnetron, which eventually trickled down into recreational boats…
Radar has been around in its standard form for a long time

Powerful pulse at fixed frequency.
Pulse propagates outwards.
Radar switches to receive mode to listen for reflections.
Delay of reflected pulse returning to the receiver is measured.
Antenna angle at the time of pulse transmission equals the direction of the object.

Pulse Radar Principals

User expertise required– Blurs and distorts objects, making it difficult to interpret surroundings and
navigate safely
– Obscures objects closest to boat, where visibility is most important forcollision avoidance
– Difficulty distinguishing targets from clutter - requires experience to safely
operate
Inconvenient installation and operation– Magnetron takes several minutes to warm up
– Magnetron has limited life, and is expensive to replace
– Power draw is impractical for many small boats and most sailboats
– Emissions require mounting away from humans and other electronicequipment
Not a user-friendly technology
Pulse Radar - weaknesses

Pulse Radar Microwave pulses with a thermionic device (magnetron)
Ancient technology sending out bursts of very high powermicrowave energy periodically
FMCW radar is different: Firstly it is solid state – i.e. the transmitter is a semiconductor
device, not based on thermionic valve technology.
Secondly it transmits continuously, not in pulses.
Thirdly it measures the time of the echo not by listening to a
received pulse but by varying the frequency of the transmittedsignal and detecting the shift in frequency in the received echo.
Hence FMCW – Frequency Modulated Continuous Wave.
Solid State vs valve technology
Broadband vs Pulse

FMCW = Frequency Modulated Continuous Wave Transmits a ‘rising tone’ (Tx wave) with linear increasing frequency
The wave propagates out from the transmitter retaining the frequency it had when itwas transmitted. If it reflects off an object, it will return to the receiver, still at the frequency it had
when originally transmitted. Meanwhile the transmitter continues to output an increasing frequency
Frequency Modulation over time is the key

• The difference in the currently transmitted and currently receivedfrequencies, coupled with the known rate of frequency increase, allows atime of flight to be calculated, from which we can calculate a distance.

At any instant in time,
Tx freq is higher thanRx freq

Broadband Radar – Unique Advantages
1. “Revolutionary improvement in situational awareness”
The best short range resolution and target discrimination of any X band marine radar
–
Radar is finally easy enough for a novice: no “tune control” – Sea and rain clutter rejection is 5-10 times better than
pulse radar
– Navigation is truly easy, even at an unprecedented 1/32nm rangeand clarity within 2-3 m of dome.
– No “main bang” or close range side-lobe distortion

Broadband Radar – Unique Advantages100% Solid State Design
2. “Start faster, go longer”
100% solid state RF design – no magnetron! – provides InstantOn™ power up capability and low power consumption
– Eliminate 2-3 minute warm-up time typical of magnetron pulse radars
– Conserve power; standby drain less than one quarter of the best 2kWradar – especially great for sailboats and smaller power boats
– No limit on transmit usage lifetime – typically 2,000 hours in amagnetron pulse radar

3 “Incredibly approachable”
Practically imperceptible RF transmit emissions and flexible installation setupallows you to mount the radome anywhere
– Extremely safe - less than 1/10th the transmitted emissions of a mobilephone; mount at any proximity to passengers
– Super small custom 13.5mm RJ45 connector and 9mm round connectorizedradar cable allows simple bridge tube installations, and provides compatibilitywith a wide range of Navico multifunction displays and heading sensors

Proven safe
Conclusion: Human exposure level to radiation anywhere outside theradome diameter is well below the general public safety emission level of 10 W/m2… including the possible case of mechanical failure of the motoror drive belt with the antenna pointing into a fixed direction.
