A Short History of Radar Radar has been around in its standard form for a long time

 In 1917, Nikola Tesla first established the principles for primitive radar units  In 1935, The British invented and patented the first radar for aircraft defense  In 1950, Decca introduced the first marine pulse radar utilizing a magnetron, which eventually trickled down into recreational boats…

Pulse Radar Principals Power 100 nsec Fixed Frequency : 9.4GHz Transmitted Object

Radar

Reflected

    

Powerful pulse at fixed frequency. Time 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 - weaknesses Not a user-friendly technology

 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 for collision 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 electronic

equipment

Broadband vs Pulse Solid State vs valve technology

Pulse Radar  Microwave pulses with a thermionic device (magnetron)  Ancient technology sending out bursts of very high power microwave 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 transmitted signal and detecting the shift in frequency in the received echo.  Hence FMCW – Frequency Modulated Continuous Wave.

Broadband Technology – how it works Frequency Modulation over time is the key

Frequency 9.41GHz 9.4GHz 1ms

4ms

Time  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 it was 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

Broadband Technology – how it works Frequency difference in transmitted and received signals

Frequenc y

Tx

Rx

– retains same frequency it had when it was transmitted

At any instant in time, Tx freq is higher than Rx freq

Time

Time delay

• 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 we can calculate a distance.

Broadband Radar – Unique Advantages Resolution and target discrimination

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 range and clarity within 2-3 m of dome. – No “main bang” or close range side-lobe distortion

Page 14

Broadband Radar – Unique Advantages 100% 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 2kW

radar – especially great for sailboats and smaller power boats

– No limit on transmit usage lifetime – typically 2,000 hours in a

magnetron pulse radar

Navico’s Broadband Radar™ Unique Advantages

3 “Incredibly approachable” Practically imperceptible RF transmit emissions and flexible installation setup allows you to mount the radome anywhere – Extremely safe - less than 1/10th the transmitted emissions of a mobile

phone; mount at any proximity to passengers

– Super small custom 13.5mm RJ45 connector and 9mm round connectorized

radar cable allows simple bridge tube installations, and provides compatibility with a wide range of Navico multifunction displays and heading sensors

Navico’s Broadband Radar™ Proven safe

Safe Distance

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

Navico’s Broadband Radar™ Market opportunity  Complements current large boat customer’s radar 



Short range resolution, target discrimination and clutter performance provide benefits in harbors and tight spots Expected to be installed in addition to high power open arrays more commonly than replacement of existing antenna

Target Market (units/year)

25-27kW 250 20m+ 10-12kW



Serves current small boat customer’s radar better   



Finds radar image hard to understand and adjust Frustrated by poor target discrimination and clutter rejection performance Limited space for safe mounting

Opens up new market where radar is not currently fitted  

Power supply is limited Limited space for safe mounting
