Research on Radar System Compatibility and Data Processing of Low-Altitude Small Target Detection

In response to the problem of low-altitude small target detection, this paper analyzes the impact of land clutter on radar anti-interference performance, studies the weight selection problem of sidelobe cancelling (SLC) for continuous pulses in complex environments, analyzes the influence of multipath effects, and proposes improvement methods. Through simulation experiments, the necessity of performing Moving Target Indicator (MTI) to suppress clutter before SLC has been verified; Comparative analysis of the impact of different SLC weight selections on subsequent target ranging and speed measurement performance in complex environments; Analyzed the impact of multipath effects on low-altitude target detection and verified the reliability of the method in improving multipath effects.
