The design of unimodular sequence train with low central and recurrent autocorrelation sidelobes is considered. The design problem is formulated as a minimisation of the integrated energy in central and recurrent autocorrelations with user‐supplied weights and an iterative method is proposed for it. The proposed method is computationally efficient, as its main computation can be implemented using FFT. Numeric results are reported to validate the proposed method.
