相控阵导引头位标器稳定跟踪控制仿真

摘要

The problem of how to control the gimbal strap stabilization platform of a phase array seeker is studied. The beam space scanning is available by controlling array transmitting wave front through a phase shifter embedded in the antenna array element. This kind of phase array radar can solve the quick scanning problem and accomplish target tracking. Besides, the disturbing influence to accuracy of target tracking due to missile body attitude movement can be eliminated during target tracking, and the good tracking property to static or moving targets is guaranteed. In order to decrease the influence of missle motion on the target measur-ing, a strapdown stabilization platform is used to maintain antenna's stabitity for a radar seeker. Based on the compensation principle, angle compensation algorithms are deduced and simulated.%研究了相控阵导引头位标器捷联稳定平台的控制问题.相控阵雷达通过嵌入天线阵元的移相器对阵面辐射波前进行控制,实现波束的空间扫描.这种体制的相控阵雷达可解决快速扫描问题,完成对目标的跟踪.在跟踪的同时需要消除由于导弹弹体姿态运动产生的对目标跟踪精度的扰动影响,同时保证稳定平台能够较好地跟踪固定目标或运动目标.对于雷达导引头,为了消除弹体姿态变化对目标测量的影响,采用捷联式稳定平台来实现天线的稳定.基于补充原理,采用了角位置补偿法进行了数字仿真研究.
