Optimization of Orthogonal Discrete Frequency-Coding Waveform Based on Modified Genetic Algorithm for MIMO Radar

Abstract

A modified genetic algorithm (GA) is proposed to numerically design orthogonal discrete frequency-coding waveforms (DFCWs) which have good aperiodic autocorrelation and cross-correlation properties for orthogonal multiple input multiple output (MIMO) radar. Some of the designed results are presented, and their correlation properties are better than other known in the literature. The effect of Doppler frequency shift on the performance of these signals and ambiguity function are investigated. The simulation results and comparisons show that the proposed algorithm is more effective for the design of DFCWs with superior aperiodic correlation.
