Pattern synthesis of MIMO radar based on chaotic differential evolution algorithm

A Chaotic Differential Evolution (CDE) Algorithm based method for pattern synthesis of MIMO radar is proposed. By optimizing positions and excitation amplitude of the element in receive and transmit array, better control of side lobe level and null depth can be achieved. CDE which is proposed by introducing Chaotic Optimization (CO) mechanism to Differential Evolution (DE), the risk of getting local optimal position can be reduced, thus the premature of DE can be avoid, and the performance of global optimization is improved. Simulation results validate the effectiveness of the proposed method and superiorities.
