This report considers a method for fast bistatic association and positioning of targets in a radar system like AASR - Associative Aperture Synthesis Radar. AASR consists of a network of distributed radar stations where the stations may be used in both monostatic and bistatic modes. The stations are not assumed to have any angular resolution, which means that the sensor information is range (both monostatic and bistatic) and the corresponding doppler information. The problem of correctly matching data from one sensor with data from another sensor, where data should be matched if they stem from the same target, is called the association problem. In this report we describe a new method for fast association which uses bistatic measurements only. The main advantage, besides the fact that bistatic configurations are more numerous than monostatic ditto, is that bistatic measurements has a much better capacity to detect stealth targets.
