Abstract:

Algorithm for moving target selection in the presence of clutter and wideband jammer is presented. The proposed algorithm includes whitening filter for the interference, followed by a matched filter for the useful signal. This cascade of filters is based on higher-order statistics approach and maximum entropy pole estimations. The algorithm performance is investigated by means of the Monte Carlo simulation analysis. The obtained frequency resolution and improvement factor values ensure high quality of signal detection.
