Abstract
A large number of clutter interference signals were involved in radar echoes. Radar detection and tracking performance degrade when the signal-to-noise ratio of the echo signal is too low. Therefore, how to suppress clutter interference is a problem that is worth studying in designing. In this paper, the statistical characteristics of radar clutter were analyzed, and a clutter suppression method based on staggered MTI was proposed for the blind speed problem of traditional MTI filters. Simulation experiments verified the model and processing method of staggered filtering. The results indicated that the method improved the blind speed while effectively suppressing the clutter.
