Abstract

This paper mainly studies an adaptive MTI, through the analysis of the input signal, the spectral center of the clutter spectrum is calculated, and then combined with the zero assignment method, the most suitable filter weight coefficient is adaptively calculated, so as to achieve the purpose of calculating the appropriate MTI filtering method for the input signal with different frequency characteristics. The filtering method studied in this paper is based on zero assignment method, and the notch of the band-reject filter is set in the center of the clutter spectrum to maximize the suppression of clutter. For the estimation of the center of the clutter spectrum, it is estimated using the centroid method. The simulation results show that the proposed method has a good suppression effect on the motion clutter with narrow spectrum.
