Phase-Only Radar Waveform Design for Spectrally Dense Environments

Abstract

This paper deals with the synthesis of waveforms that optimize radar performance while satisfying multiple spectral compatibility constraints. For each shared band, precise control is imposed on the injected interference energy. Furthermore, compliance with amplifiers operating in saturation is ensured at the design stage where phase-only waveforms are considered. To tackle the resulting NP-hard optimization problem, an iterative procedure based on the coordinate descent method is introduced. Hence, some case studies are reported to highlight the effectiveness of the technique.
