随着目标运动速度的日益提高、目标散射截面积越来越小,雷达探测超高速隐身目标越来越困难,超高速目标使得目标回波与发射信号不再匹配,造成匹配增益的降低,且该类目标一般高机动飞行,也会对目标造成积累损失。文中提出了一种针对目标运动特性的精确匹配检测方法,可以在回波失配和目标机动下很好地工作,提高了对超高速隐身目标的检测概率。
With the increasing of the moving speed of the target, the target scattering cross-sectional area is getting smaller and smaller. It is more and more difficult for the radar to detect the stealthy target of ultra-high speed. The ultra-high speed target makes the target echo and the transmitting signal no longer match, Such targets in general high-maneuver, but also on the target caused the accumulation of losses. In this paper, a precise matching detection method for target motion characteristics is proposed, which can work well under the condition of echo mismatch and target maneuver, and improve the detection probability of stealthy targets.
