Abstract: ABSTRACT This letter presents an efficient algorithm for designing binary phase‐coded sequences with low peak sidelobe level (PSL) for multiple‐input multiple‐output (MIMO) radar applications. The algorithm features a log‐sum‐exp function (LSEF)‐based fitness function and a vectorized recursive computation method, substantially reducing computational complexity compared to conventional approaches. A two‐stage search strategy effectively balances between local exploitation and global exploration. Numerical results demonstrate that the proposed algorithm achieves comparable PSL performance to state‐of‐the‐art algorithms with enhanced computational efficiency in monostatic cases, while exhibiting superior PSL performance in MIMO scenarios.
