3-D Imaging Algorithm for Targets with Micro-Motion Based on HRRP Sequence
Three-dimensional (3-D) radar imaging has been widely used in target scattering diagnosis, modeling and target identification. In this paper, 3-D imaging algorithm for targets with micro-motion based on high resolution range profile (HRRP) sequence is presented. Aiming at the difficulty of getting look angle parameters of the radar directly and considering the precession feature of targets with micro-motions, a way of turning precession parameters into angle parameters indirectly is proposed. Meanwhile, for the scattering centers association, two methods are discussed and compared. Finally, performance analysis under the influence of related factors is also covered and the parameter constraints are given, and thus provide a reference for the design of 3-D radar imaging system. Simulation results are presented in the end, which prove the efficiency of the proposed method.
