Paper Abstract

The Shape Intersection Technique uses image processing methods to locate a radar transmitter, receiver or both from radar signals collected passively with an omnidirectional antenna. The method is based on searching a set of transmitter positions, receiver positions and radar parameters until the predicted locations of bistatic reflectors optimally matches a feature reference data base of known locations. Reflector locations are obtained by converting measured pulse times of arrival to two-dimensional locations based on a geometric model of the bistatic radar geometry. The feature reference data base can be extracted from digital terrain elevation data, cultural feature data or directly from registered radar data. The technique has been tested on synthetic data, data from cooperative radars and data from non-cooperative radars. Geolocation can be very accurate when the map features include adequate patterns.
