摘　　要：针对传统单脉冲跟踪方式中难以同时兼顾跟踪伺服系统的稳定性和高精度问题,采用了一种计算机辅助跟踪技术。介绍了技术的原理并给出了具体的实现方法,然后用Matlab的Simulink工具箱进行了仿真。仿真结果表明,采用计算机辅助跟踪技术可以在不影响跟踪伺服系统稳定性的前提下,大大提高其跟踪精度。The stability and high precision of tracking servo system can not be reached at the same time by using traditional monopulse tracking method, so a computer -aided tracking technology is adopted in tracking servo system for this problem. In this paper, the basic principles and detailed realization approach of this technology are presented, then a simulation performed using Matlab Simulink toolbox. The result of simulation shows that using computer - aided tracking technology can improve the tracking precision of tracking servo system greatly without influencing its stability.
