Abstract：Compared with the monostatic radar, micro-Doppler effect in bistatic radar has many differences due to its spatial complexity. In this paper, micro-Doppler effect of target with rotating parts is derived in the bistatic ISAR system. Characteristics and manifestation of micro-motion part in the range–slow-time plane is also analyzed. According to the effect produced by the system’s spatial relationship, a modified extended Hough transform is proposed to extract the micro-motion information from the range–slow-time plane. Simulations verify the correctness and effectiveness of the method in bistatic ISAR system.
