Abstract
Design of orthogonal code sets with ideal correlation properties is crucial for orthogonal Multiple Input Multiple Output (MIMO) radar. A modified Genetic Algorithm (GA) is proposed to numerically design orthogonal Discrete Frequency-Coding Waveforms (DFCWs) with good correlation properties for MIMO radar. Some of the designed results are presented, and their correlation properties are better than those presented in literatures. The effect of Doppler frequency shift on the performance of these signals is simply investigated. Simulation results and comparisons show that the proposed algorithm is more effective for the design of DFCWs with superior aperiodic correlation properties.
