Precession Period Extraction of Ballistic Missile Based on Radar Measurement

A method of extracting the precession period of ballistic missiles (BM) in the midcourse phase of their ballistic trajectories with radar cross section (RCS) sequence was presented. The motion of ballistic missiles in the midcourse phase was analyzed and modeled. Then the relationship between the precession period of missile warhead and its RCS sequence was discussed. Based on the variation characteristics flying in the RCS sequence, a method of extracting the precession period was proposed. Simulation results demonstrated the efficiency of the method
