【 摘 要 】

This paper gives numerical method for unimodular sequences design with low peak sidelobe (PSL) level of aperiodic autocorrelation function (AACF). The result of numerical optimization for design of unimodular sequences of length N = 1024 with smallest today PSL ≈ 2.618 is shown. Such sequences are useful for resolution and parameter estimation in radar applications due to their large signal-to-noise ratio.
