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 development of modern military technology, the moving target flies faster, and the radar cross section (RCS) of the target is smaller. As a result, the high-speed stealth target can't be continuously detected effectively by radar, and the transmitting signal can't be matched with the echo of the target, which leads to a decrease in the matching gain. In addition, the highspeed stealth target moves with high maneuvering ability, which can result in an integration loss. In this paper, an accurate matched filtering and detection method is proposed for high-speed stealth target. The proposed method performs well with echo mismatching and target maneuvering, and it increases the detection probability for the high-speed stealth target.
