Adaptive clutter map detector in nonhomogeneous environment

摘要: The Ordered Data Variability (ODV) technique is introduced into hybrid clutter map/L-CFAR technique, which used to process the echoes on map spatially. new method called as Clutter Map/ODV (CM/ODV) technique. An analytic expression of detection probability in homogeneous environment presented, and performance three different situations nonhomogeneous analyzed. CM/ODV can censor interfering targets adaptively prevent masking effect, moreover, it doesn't need any priori information, so kind performs robustly.
