Abstract : An airborne direction-finding technique capable of handling multiple emitters was developed. An adaptive gate size was introduced in the track correlations based on covariance relations of established tracks and observations. Track files were generated based upon the existence of various target parameters; i.e., frequency, pulse repetition frequency, pulse width and direction-of-arrival. To test the angular resolution capability of the filter, emitters in close proximity to each other with identical electronic characteristics were used in the simulation. Target locations are calculated in a cartesian coordinate system where the sphericity of the earth is taken into account, and with appropriate coordinate transformation computational simplicity is preserved.
