A W-band airborne interrupted FMCW imaging radar

A 94GHz imaging radar with its associated gimbals for stabilisation and scanning has been developed as an airborne test-bed to evaluate radar aided navigation and guidance algorithms. Preliminary results from helicopter based flight tests show sufficient contrast between selected features (including runways) and their surroundings for both computer and human pilot based guidance. Feature extraction and matching algorithms have shown this system to be more accurate than that that achieved by GPS.
