摘要
Abstract
In Multiple-Input Multiple-Output(MIMO) radar imaging systems, the configuration of antenna array, as one of the key techniques, has great effects on image quality. Based on the imaging model of MIMO radar, in order to compromise the number of antennas and the performance of the array, the sparse array design method taking advantage of the equivalent virtual array concept is discussed, and the designed structure of the sparse array based on far field is optimized. Simulation results show that the grading lobes of the proposed array are lower than -50 dB in 120-150 GHz.关键词
