Abstract:
The objective of this analytical study was to develop an optimal emitter location algorithm using Kalman filtering techniques to filter emitter bearing angles-of-arrival information in an airborne, multi-emitter environment. Since emitter and aircraft navigation data were sampled at discrete time intervals, discrete sequential estimation techniques were used within a software computer program which initially sorted data, filtered emitter bearing angles- of-arrival to obtain optimal estimates, and computed emitter positions in latitudelongitude coordinates using various emitter location algorithms. An error analysis was performed on the emitter location algorithms to determine relative accuracy of the different techniques. Extended Kalman filtering was also considered as an alternate approach to the emitter location algorithm.
