考虑目标机体坐标系与地面雷达坐标系之间的坐标转换关系，计算得到了雷达视线在目标坐标系中的方位角和高低角。通过对典型目标建模，得到目标全空域的静态RCS值，并利用Matlab仿真分析了动态目标的RCS特性和突防概率变化。仿真结果表明：不同飞行高度以及不同的航路捷径均可以影响机动目标的RCS序列，且当目标作适当的俯仰机动后，减小了目标RCS，给作战飞机设计飞行航线提供仿真依据，给成功实现突防带来一定影响。

Considering the inter coordinate transformation relation between target body coordinate and ground-based radar coordinate,the azimuth and elevation of line of sight of radar in target body coordinate is analysed in the paper. All airspace static RCS can available by establishing typical target modeling and using Matlab to simulate the RCS characteristic and penetration probability of dynamic target. The simulation results show that different altitude and route shortcut both can influence the RCS series of maneuver target,and the RCS is lower when some proper pitch movement is adopted. Also the simulation provided a foundation for design of flight track and brings certain effect to the penetration of stealth aircrafts.
