Abstract

For gate lobe suppression of distributed array, a method based on genetic algorithm combining array layout optimization and frequency synthesis is proposed to suppress grating lobe. This paper first introduces the principle of gate lobe generation and the basic principle of genetic algorithm, then the method of gate lobe suppression by array layout optimization based on genetic algorithm and the method of gate lobe suppression by frequency synthesis based on genetic algorithm are given. Finally, the method of combining space and frequency to restrain grating lobe based on genetic algorithm is presented. Simulation analysis shows that the combination of space and frequency has better suppression effect than the single array layout optimization or frequency synthesis.
