地面雷达,由于周围地物影响,往往在显示器荧光屏上出现一大片诸如建筑物、小山丘等地物回波;海面雷达,由于海浪起伏回波的影响,在近距离内有一大片海浪杂波;空载雷达,由于地面反射杂波的干扰,也有一大片杂波;如果雷达要在云雨、消极干扰中探测目标,也存在云雨、消极干扰回波的影响,在荧光屏上很难将要探测的运动目标区分出来。因此,为了使雷达在各种复杂地形和干扰环境下都能工作,必须解决抗 Due to the influence of surrounding objects, ground-based radars often show a large number of echoes such as buildings and hills on the screen of a display. The surface radar has a large clutter of waves at close range due to the ups and downs of sea waves. No-load radar, due to the interference of ground-reflection clutter, also has a large clutter; if the radar is to detect the target in the cloud rain, negative interference, there is cloud rain, negative interference echo, the screen is difficult to detect the motion of the screen Differentiate the goal. Therefore, in order to make the radar work in a variety of complex terrain and interference environment, we must solve the resistance
