  clutter edges
    Under Swerling Ⅱ assumption ,the analytic expressions of P_(fa). P_d and ADT are derived for the detector. By comparison with other schemes ,the results show that the detection performance of MOSTM is improved both in homogenius background and in nonhomogenious environment caused by strong interfeting targets and clutter edges ,while the sample sorting time of MOSTM is less than half of hat of OS.
    在SwerlingII型目标假设下,推导出了它的P_(fa)、P_d和度量ADT的解析表达式,并与其它方案进行了比较,分析结果表明,MOSTM在均匀背影及多目标和杂波边缘引起的非均匀背景中,它的性能比OS和GOSCA获得了改善,并且它的样本排序时间还不到OS的一半。

Again, the isolated target at range bin 150 is detected and the target at range bin 230 is masked by the clutter edge.
      
Figure 19 shows the loss in IF around the clutter edge scenarios of Figure 18, and show that the losses can be substantial.
      
Think about a weak edge at object boundary, or a strong clutter edge in the background.

However, the false alarm rate performance of OSSO-CFAR(Constant False Alarm Rate) scheme at clutter edges is worsen with increasing the postdetection integrated pulses.
      
Notice that after learning, not only clutter edges are suppressed but also the correct edge polarities are recovered.
      
Output from a directional Gaussian edge detector shows that there are many clutter edges present as potential distractors.
      
We want to inhibit clutter edges and recover correct polarity.
