无源探测中微弱目标的多步检测算法研究
Multi-stage detection algorithm of weak target in passive detection
摘要
Abstract
To overcome the problem that masking effect can seriously affect the detection performance of weak far away target, a multi-stage detection algorithm is proposed.This algorithm adopts the extensive cancellation algorithm to remove the direct signal and clutter signal that are caused by masking effect, and uses optimized CLEAN algorithm to remove strong target echo nearby.By removing strong target echo gradually,better detection performance of weak target echo is achieved.Simu-lation results prove the new algorithm can estimate position of the weak target more accurately and detect the target better in strong interference background with less calculation.关键词
