The design of orthogonal waveforms with discrete frequency codes for MIMO radars

MIMO radars can effectively improve their performances by transmitting orthogonal signals. Designing orthogonal signals with low autocorrelation sidelobe peak （ASP） and cross- correlation peak （CP） is crucial for MIMO radars. With ASP, CP and energy as the cost function, and based on a modified genetic algorithm, a simulation is made to optimize discrete frequency codes via non-full codes. The results show that the algorithm is effective.
