Adaptive Spurious False Alarm Suppression Method for Airborne Pulse Doppler Radar

The detection performance of ground targets by airborne pulse Doppler radar is significantly impacted by the pronounced clutter resulting from ground reflections. This, in turn, leads to the presence of spurious signals surpassing the background noise level and generating false targets. To address this issue, this paper introduces an adaptive spurious suppression method suitable for airborne pulse Doppler radar. By comprehensively analyzing the spurious generation process, the proposed method leverages specific frequency and distance characteristics of spurious to dynamically suppress false alarms, with the objective of enhancing radar detection performance. Finally, the effectiveness of the proposed approach is subsequently validated through processing and analysis of real data.
