The spherical harmonics root-music

ICASSP 2016accepted

Spherical harmonics root-MUSIC (MUltiple SIgnal Classification) technique for source localization using spherical microphone array is presented in this paper. Earlier work on root-MUSIC is limited to linear and planar arrays. Root-MUSIC for planar array utilizes the concept of manifold separation an…

Ground moving target imaging by synthetic aperture radar based on an unified framework of keystone transformation

Lei Yang, Lifan Zhao, Lu Wang, Guoan Bi

ICASSP 2015accepted

This paper presents a new SAR ground moving target imaging (GMTIm) algorithm based on an unified framework of Keystone transformation (KT). To combat the inherent range-azimuth coupling, an tandem two-step strategy is designed, where the range decoupling is implemented by polar format algorithm (PFA…
