An efficient algorithm for array optimization of MIMO radar

Array optimization of MIMO radar is important to obtain better system performance. Numbers of efficient virtual array elements that can be obtained by MIMO radar are analyzed and compared among different linear array arrangement. An efficient algorithm for array optimization of MIMO radar is presented, by the algorithm, the virtual array of MIMO radar is a MR array, and the most efficient virtual sensors can be obtained. Last, the performance of MIMO radar optimized by the algorithm in this paper are compared with the conventional ULA MIMO radar, the simulation results indicates that the resolution capability of the optimized MIMO radar is better than that of ULA MIMO radar when they have the same physical sensors.
