摘要
相控阵导引头全捷联安装在弹体上,波束指向易受弹体姿态扰动影响,从而影响探测性能。需采取相应的捷联去耦措施,隔离弹体扰动,实现波束在惯性空间的指向稳定。分析了弹载相控阵导引头捷联去耦的特性,给出一种实用的相控阵导引头捷联去耦方法,通过仿真试验对导致相控阵导引头不完全解耦的因素进行了系统分析,得出满足弹载环境去耦系数需求时,对部分雷达参数设计的约束。
Because the phased array radar seeker is fixed on the missile, the beam direction is effected by the missile movement and thus the performance of radar seeker is weakened. The appropriate strap-down de- coupling method must be used to isolate the effect of missile attitude disturbance. The decoupling characteris- tic of phased array radar seeker is analysed, then a practical strap-down decoupling method for phased array radar seeker is put forward. Simulation experiment is made to analyse effect factors of decoupling mechanism.
