遮蔽区 meaning in English

shelterarea

The land clutter is useless signals for target detection caused by land terrain . the multipath effect is some kind of interference which is caused by wave reflection on terrain . the diffraction effect is the phenomenon of wave propagation into shadow region
地杂波是由地面散射引起的对目标探测无用的信号;多路径是由电磁波在地面反射所引起的干涉;衍射则是电波绕射传播到遮蔽区的现象。
