Radar Waveform Design Based on Majorization-Minimization Algorithm
Pages: 159-165
Year: Issue:  2
Journal: Radar Science and Technology

Abstract: To tackle the sophisticated radar scene,a novel method based on majorization-minimization mechanism is presented to design waveforms with low correlation sidelobes and sparse spectrum.Firstly,the unimodular waveform,in the case of minimizing the integrated sidelobe level as well as suppressing the congested spectrum,is formulated.Next,the objective function incorporating the idea of majorization-minimization is derived,and then,the MISL algorithm and the weighted spectral-MISL algorithm are proposed.Simulations demonstrate that these algorithms can obtain low integrated sidelobe level and sparse spectrum in the suppressed bands,which also performed for long waveforms.
