We apply local entropy algorithm to the clutter tracking and detect clutter edge by local entropy filter . we also develop a new method to estimate fractal dimension from clutter surface for region segmentation . regarding the different results of clutter tracking as the background information , we propose clutter feature ( cf ) - cfar detector and structuring element ( se ) - cfar detector 然后針對這兩種不同的雜波跟蹤結(jié)果,提出分別采用雜被屬性恒虛警檢測器和結(jié)構(gòu)元素恒虛警檢測器,以改善傳統(tǒng)雷達(dá)系統(tǒng)中僅采用單一恒虛警算法造成的檢測性能低下。
