Applying an adaptive technique to improve tracking filter performance

A sequential processing realizes Direction of Arrival (DOA) track performance improvement is presented. Firstly, the current position, Doppler frequency are estimated and a mathematical model is derived in order to clarify the effect of Doppler frequency (f
d
) on the estimation process. The Doppler Effect is employed within subspace concept in order to refine the target estimated current position. Secondly, target maneuver is presented to realize a more accurate association process, and also weight factor is employed within smoothing process for tracking adaptation. Simulation results are shown a high accuracy DOA tracking by presented method.
