摘要：
Spatial stepped-frequency multiple input multiple output (MIMO) array model is proposed to improve the resolution of MIMO radar. Two-sided correlation transformation (TCT) focusing algorithm and iterative power spectrum reconstruction (IPSR) algorithm are extended to this situation. TCT focusing algorithm estimates the direction of arrival (DOA) in reference frequency after focusing the signals of different frequency to the reference frequency, while IPSR estimates the DOA by reconstructing the power spectrum of different frequency signals iteratively. Simulation results show that the performance of IPSR algorithm is better than that of TCT focusing algorithm.
