A scheme to locate emitter positions using post flight processing of discrete airborne emitter bearing angles-of-arrival information and recorded aircraft position coordinates by Kalman filter techniques is developed. The signal intercept system was assumed to be operating in a multi-emitter environment and all data was sampled at discrete but time varying intervals. The aircraft position data is filtered directly in latitude and longitude and emitter locations are computed in latitude and longitude using vector methods. An extended Kalman filtering scheme is developed to compute emitter coordinates directly in latitude and longitude coordinates. Author
