基于捷联导引头去耦问题惯测注入方法研究

Research on INS injection method based on strap-down seeker decoupling

半实物仿真作为导弹打靶前的重要验证环节,在导弹研制定型过程中作用日益重要,半实物仿真系统要具备全面考核导弹性能的能力。但随着导弹性能的提升,出现了仿真过程中导弹弹体姿态角变化方位超出现有半实物仿真系统飞行转台的转动范围情况。基于捷联导引头去耦问题,设计了一种惯测注入式仿真方法,解决转台转动范围不满足弹体姿态角变化范围的问题,提升半实物仿真系统仿真能力。

As an important verification link before missile shooting,hardware in the loop simulation plays an increasingly important role in the missile finalization process.The hardware in the loop simulation system should have the ability to comprehensively evaluate the missile performance.However,with the improvement of missile performance,in hardware in the loop simulation system,the range of missile attitude angle may exceed the rotation range of the flight turntable.Based on strap-down seeker decoupling,an injection simulation method is designed to solve the problem and improve the simulation ability of the hardware in the loop simulation system.
