On the application of adaptive filters in radar signal detection
Abstract
Adaptive filtering of Doppler signals for the case of a pulsed radar is analyzed as a problem in spectrum estimation. The limitations in a radar environment are the number of hits received, the speed of processing, sliding of Doppler frequency across Doppler bins, and the nonstationary nature of the background clutter. The adaptive filter is considered to succeed the traditional MTI processor with two-pulse canceler. Three types of algorithms are considered for Doppler-frequency estimation, and the results of simulation studies are presented.
