摘　　要：随着临近空间战略价值的显现,临近空间高速目标的跟踪成为国土防空领域研究的一个热点。临近空间高超声速飞行器具有高机动突防能力,且运动轨迹没有规律,使用常规滤波方法难以实现稳定跟踪。提出一种衰减记忆最小二乘算法,该算法不依赖特定的运动方程,鲁棒性强。仿真实验表明,新算法可以稳定跟踪高超声速飞行器,机动飞行段跟踪连续光滑,具有较高的跟踪精度。Along with the tactic value of near-space occurs, tracking high ultrasonic targets in near- space has become a research hot spot in national air defense domain. The high ultrasonic vehicles in near-space have ability of well maneuvering and penetration, and the motion track is not regular, so the stable tracking is difficult by using conventional filtering methods. This paper puts forward a kind of fading memory least square tracking algorithm. This new algorithm avoids relying on spe- cial motion equation and has strong robust. The simulation experiments show that the new algo- rithm can stably track high ultrasonic vehicles and the tracking to the targets in mobile flight phase is continuous and smooth, and the tracking precision is higher.
