天基拦截器轨道选择研究

Researching on Choice of Space Interceptor Orbit

针对给定高度的目标,对天基拦截器轨道的选择进行初步研究。其仿真从拦截范围、变轨所需速度增量、拦截所需时间、碰撞时可获得动能等方面分析初始轨道高度的选择。一般情况下,轨道高度越低,偏心率越小,两航天器间初始角度差就越大;轨道高度越低,偏心率越大,所需速度增量就越大;轨道高度越高,偏心率越小,所需的时间就越长;轨道高度越高,偏心率越大,天基拦截器到达相关点的速度就越大。

Carry out research on choice of space interceptor orbit according to present height target. Acquire initial orbit height choice based on simulation analysis for interceptor area, orbit-changing acceleration, interceptor time, and collision power. Generally, the orbit height is lower, the eccentricity rate is smaller and the initial angle minus among two spaceships is larger; while the orbit height is higher, the eccentricity rate is bigger and the speed of space interceptor is higher.
