空间拦截末制导段能量需求分析

为了研究空间拦截末制导段的能量需求,对导航与测轨误差模式和空间拦截交会条件进行了分析,并建立末制导段仿真模型。使用Monte-Carlo法仿真,获得不同交会角下和不同拦截概率下拦截器所需的能量,并讨论了交会角和相对速度对拦截器能量需求的影响。

Energy required analysis of space intercept terminal guidance

To investigate the energy required of terminal guidance phase of space intercept,the error modes of navigation and orbit measure are analyzed.The crossing condition is studied.The simulation model is also established.The terminal guidance phase utilizes proportional navigation and Double-Plane-Control method,and simulations have be done in different crossing angle.Monte Carlo method is mainly used to form random sample the error of navigation and orbit measure.The energy required of interceptor is obtained in different rendezvous angle and different hit probability by using Monte Carlo simulation.The impact of rendezvous angle and relative velocity to the energy required is discussed.
