摘　　要：对于小型化雷达导引头,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。基于补偿原理,对弹载天线平台捷联稳定的两种实现方法———角速度补偿法和角位置补偿法进行了比较研究,给出了具体的补偿算法及其特性分析,同时对分别采用两种补偿方法的系统稳定效果进行了数值仿真。结果表明,在测量误差较小的情况下,两种方法均可实现天线的捷联稳定,而角速度补偿法对测量误差比较敏感。因此,在环境比较恶劣的稳定平台应用中,角位置补偿法比角速度补偿法具有更大的优越性。In order to decrease the influence of the missile motion on the target measuring, strapdown stabilization platform is proposed and applied to stabilize antenna for a small-size radar seeker. Based on compensation principle, two strapdown stabilization methods for airborne antenna platform are compared, Rate compensation and angle com- pensation algorithms are deduced and analyzed. Stabilizing effect is simulated. Results indicate that two methods can achieve strapdown stability with smaller measuring error, however, rate compensation is more sensitive to measuring error. Therefore, angle compensation is more applicable under relatively severe circumstances.
