Optimal Design of Microphone Random Array Based on Improved Genetic Algorithm
Aiming at the problem of spatial confusion caused by uniform sampling intervals in microphone regular arrays, an optimized design method for microphone random arrays based on an improved genetic algorithm is proposed. The results show that the optimized 24-channel random array can control the main lobe width loss at a low level while the side lobes are significantly suppressed. Compared with uniform array, the genetic algorithm designed in this paper can be used to optimize the array layout and obtain better array directivity.
