摘　　要：随着导弹突防技术的发展,对及早获取进攻导弹特征信息的要求越来越高。利用弹道导弹在主动(?)的运动轨迹特征,提取其姿态角变化规律,根据姿态角的变化,采用物理光学法(PO)与等效电磁流法(MEC相结合的方法快速计算弹道导弹动态RCS序列,并与分离后的RCS序列进行比较,结果表明弹道导弹主动(?)的动态RCS序列充分体现了导弹的运动特性,并且利用其可初步提取导弹的分离时刻与分离速度。With development of missile penetration technology, higher and higher demand is required eagerly to achieve the characteristics of attack missile early. Based on the characteristics of boost-phase of the ballistic missile, the regularity for change of attitude angle was got. With the change of attitude angle, the RCS time series of ballistic missile were calculated by the combination of physical optics （PO） and the method of equivalent current, and the resuh was compared with the detached missile. The result shows that the RCS time series of the boost-phase of ballistic missile embody the motion characteristics of missile, and time and velocity of detachment can be achieved pre- liminarily.
