Comparison of Directional WaveGuide Radar with Directional WaveRider Buoy
Abstract Down looking FMCW radars for measuring water level, tides and wave height have been in use for 25 years. A combination of three down looking FMCW radars, mounted on an o↵ shore location, can be used to accurately measure ocean wave height and wave direction. At locations where an o↵shore mounting construction is readily available, the major advantage of this relatively new ...

Intercomparison of a WaveGuide radar and two Directional Waveriders
Down-looking FMCW radars for wave measurements are in use already for 25 years. They have proved to be very robust and maintenance is hardly needed. Now the prices of FMCW radars came down they are being more widely applied for water level, tide, harbour oscillations and wave height at sea, lakes and rivers. Radacs WaveGuide was introduced in 1998 based upon a commercial tank radar, first Enrafs ...

Technology transfer is more important than innovation
Innovation, we are told, is the key to a successful manufacturing economy. Invent and patent something and you will make money on every one made - if it is mass produced you get an on-going income. Tony Ingham of Sensor Technology Ltd looks at his experience over two decades and tries to draw some general principles that may help Britain in its new ambition to rebuild the manufacturing base. We ...
