Quasi-Optical CWFM Radar

The picture shows a quasi-optical mm-wave radar.(It looks best in 32k colours or more!)

This system uses a continuous output whose frequency is swept up and down. This techinque is called Continuous Wave Frequency Modulation (CWFM) radar. The system operates at frequencies from 80GHz up to 140GHz and can provide cm range resolution even at very short ranges (down essentially to zero). systems like this are being considered for tasks as varied as car collision avoidance and missile 'seeker heads'.
