Constant modulus sequence set with low peak side-lobe level is a necessity\nfor enhancing the performance of modern active sensing systems like Multiple\nInput Multiple Output (MIMO) RADARs. In this paper, we consider the problem of\ndesigning a constant modulus sequence set by minimizing the peak side-lobe\nlevel, which can be cast as a non-convex minimax problem, and propose a\nMajorization-Minimization technique based iterative monotonic algorithm. The\niterative steps of our algorithm are computationally not very demanding and\nthey can be efficiently implemented via Fast Fourier Transform (FFT)\noperations. We also establish the convergence of our proposed algorithm and\ndiscuss the computational and space complexities of the algorithm. Finally,\nthrough numerical simulations, we illustrate the performance of our method with\nthe state-of-the-art methods. To highlight the potential of our approach, we\nevaluate the performance of the sequence set designed via our approach in the\ncontext of probing sequence set design for MIMO RADAR angle-range imaging\napplication and show results exhibiting good performance of our method when\ncompared with other commonly used sequence set design approaches.\n
