Abstract

Wide low-gain transmitting beam and long time integration are adopted in the orthogonal signal MIMO radar to survey the interested area. The range migration of moving target is a pivotal problem faced in the MIMO radar. Orthogonal LFM signal is one of the most familiar waveforms in MIMO radar, and this paper discusses the range migration compensation problem in the MIMO radar using Stepped Frequency Division Linear Frequency Modulation (SFDLFM) signal. A new compensation method based on the proper range- direction coupling relationship is put forward. It can achieve a good compensation effect with low computation complexity. Theoretical deduction and simulation results demonstrate the validity of this method.
