摘要
Abstract
Stepped frequency synthesis processing technology is a method easily realized in radar to obtain high-resolution range profile.However,the stepped frequency radar is sensitive to the target's motions,thus velocity compensation is needed in stepped frequency synthesis processing.Because the ordinary imaging method for single target is not suitable for multiple targets with different velocities,the imaging method for multiple targets is discussed in this paper.The multi-target image processing method divides the pulse compression data into several segments.And then range realignment,velocity compensation,synthesis imaging,and range profile splice are applied to each data segment to obtain the complete range profile containing multiple targets.The simulation results validate the effectiveness of this algorithm.关键词
