摘要：

Due to the multi-antenna structure in both transmitting and receiving arrays, the imaging performance of a Multiple-Input Multiple-Output (MIMO) imaging radar is quite sensitive to the inter-channel errors. To compensate these errors, an iterative calibration method for the 3D MIMO imaging radar is proposed based on the minimum entropy technology in this paper. This method can achieve a joint estimation of the amplitude and phase errors and be performed based on the echo of the natural scene instead of placing prominent point targets. Finally, the correctness and validity of the proposed method are verified by a simulation and an experiment.
