Polyphase Orthogonal Code Design for MIMO Radar Systems

Multiple Input Multiple Output (MIMO) radar can effectively improve radar performance by transmitting specially designed orthogonal signals. A novel hybrid algorithm is presented to numerically optimize such orthogonal code sets. The proposed algorithm integrates a statistical Genetic Algorithm (GA) with the traditional iterative code selection method. The simulation results show that the proposed algorithm is effective for the design of polyphase signals used in MIMO radar.
