A New Compensation Method of HRRP for Ballistic Targets

Abstract:

The influence on the high range resolution profile (HRRP) of the ballistic target caused by high speed motion is analyzed based on the wideband radar de-chirping echo. According to the characters of ballistic target echo ambiguity diagram (AD), the auto-terms line of echo ambiguity function is extracted from the corresponding binary image by skeleton extraction technology. Therefore, the problem of chirp rate estimation is transformed into the least square (LS) estimation problem. Furthermore, a new motion compensation method of HRRP for ballistic targets is proposed based on the ambiguity diagram and least square estimation theory. Simulation results show that the method can eliminate the influence of the high speed motion effectively, and it has a high estimate accuracy and low computational cost.
