Abstract

Accurate direction-of-arrival (DOA) estimation is a core problem in array signal processing with applicationsin radar, sonar, and wireless communications. Classical MUSIC-based techniques provide high angular resolution butoften exhibit performance degradation in low signal-to-noise ratio environments and in the presence of closely spaced sources. In this paper, a Sigmoid-Enhanced Adaptive Weighted MUSIC (SEAW-MUSIC)
