The study of effective accumulation algorithm of the missile-borne chirp radar

In view of the envelope migration problem occurs when high speed missile borne chirp radar detects low-speed moving target, in the paper, the method of applying the missile borne inertial navigation information and envelope interpolation displacement method to compensate envelope movement is proposed to improve the accumulation performance of missile borne chirp radar. Then, the influence of missile borne chirp radar envelope movement to accumulation and the principle of envelope interpolation displacement compensation algorithm are analyzed. Finally, the simulation results show the effectiveness of the method.
