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
地雜波是由地面散射引起的對目標探測無用的信號;多路徑是由電磁波在地面反射所引起的干涉;衍射則是電波繞射傳播到遮蔽區的現象。 -
