Aimed at the designing issue of discrete frequency-coding waveforms in a MIMO radar system, a method to optimally combine the selection of frequency-coding sequence using the genetic algorithm was presented. First, the cost function of waveform design was improved, and the selection, crossover and mutation operator of genetic algorithm was designed in terms of the characteristics of discrete frequency-coding. Finally, the design results were analyzed, which shows that the proposed method outperforms simulated annealing algorithm.
