A algorithm on improved sparrow search (ISSA) proposed this paper. Firstly, a probabilistic following strategy optimize (SSA), it can improve global capability algorithm. Secondly, adaptive Cauchy–Gaussian mutation are used avoid falling into situation, more high‐quality areas searched extremum escape ability convergence performance Finally, peak sidelobe level (PSLL) as fitness function adaptively position elements. Experimental simulations show that approach has good main lobe response low response. In planar array, decreases by −1.41 dB compared with genetic (GA) 0.69 lower than SSA. linear −1.09 differential evolution 0.40 arrays significantly enhances accuracy robustness antenna error estimation.
