Abstract: 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.
