Peak sidelobe level reduction (PSLR) is crucial in the application of large-scale array antenna. which directly determines the radiation performance of array antenna. We study the PSLR of subarray level aperiodic arrays and propose three array structures: dislocated subarrays with uniform elements (DSUE). uniform subarrays with random elements (USRE). https://www.markbroyard.com/limited-time-depileve-easy-clean-wax-warmer-cleaner-220-ml-discount-top-mega/
