Compressive Sensing Based Specular Multipath Exploitation For Through-The-Wall Radar Imaging
2013 IEEE INTERNATIONAL CONFERENCE ON ACOUSTICS, SPEECH AND SIGNAL PROCESSING (ICASSP)(2013)
摘要
Multipath propagation can create ghost targets that severely affect the reconstruction quality of through-the-wall radar images. We propose a compressive sensing (CS) based reconstruction method, which inverts a specular multipath model through exploitation of the structured sparsity in the scene. This allows suppression of the ghost targets and increased signal-to-clutter ratio at the target locations, leading to 'clean' images of stationary scenes. Simulation results demonstrate the effectiveness of the proposed approach.
