摘要
Lambert算法设计的拦截制导律在飞行时间较长时存在上百公里级的脱靶量。通过STK中的Astrogator模块进行修正,利用其中的高精度轨道机动仿真模型模拟真实摄动环境,利用其中的Target Sequence子模块进行修正参数的设置并执行修正过程。算例表明,对脉冲和有限推力拦截制导律进行修正后,均能够实现零脱靶量,而且不需要增加燃料消耗,验证了算法的有效性和便利性。
The interception guidance law designed by Lambert algorithm exists hundreds of kilometers miss-distance when flying time is long. STK/Astrogator module was adopted to correct this flying error, in which high precision orbital maneuver models were used to simulate the real perturbation environment, and target sequence sub-module was used to set correction parameters and execute the correction procedure. Simulation results show that corrected impulse and finite thrust interception guidance law can achieve zero miss-distance without extra fuel consumption, which validate the validity and convenience of this method.
