Application of sparse array and MIMO in near-range microwave imaging

SPIE Proceedings, 2011
Near range microwave imaging systems have broad application prospects in the field of concealed weapon detection, biomedical imaging, nondestructive testing, etc. In this paper, the techniques of MIMO and sparse line array are applied to near range microwave imaging, which can greatly reduce the complexity of imaging systems.

Microwave imaging with random sparse array and compressed sensing for target detection

2015 IEEE International Conference on Computational Electromagnetics, 2015
This paper presents a study of Synthetic Aperture Radar (SAR) imaging based on random sparse array (RSA) and compressed sensing (CS) for target detection. Extensive numerical experiments based on real RSA measurement data are carried out and statistical analysis is performed to compare the performances of the CS technique and back-projection (BP ...

An evaluation method for sparse microwave imaging radar system using phase diagrams

Proceedings of 2011 IEEE CIE International Conference on Radar, 2011
We propose a method based on the phase diagram tool to evaluate the sparse microwave imaging radar system. In the method, success rates of signal recovery are derived from the statistics of relative errors between the targets and the recovered signals.

Implementation of GPU-based Iterative Shrinkage-thresholding Algorithm in sparse microwave imaging

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
In this paper, we present the implementation of Iterative Shrinkage-thresholding Algorithm (ISTA) based on Graphic processing unit (GPU) parallel computation for sparse microwave imaging. First we introduce the theory of sparse microwave imaging and the mathematical model of Lq-norm regularization.

Experimental results and analysis of sparse microwave imaging from spaceborne radar raw data

Science China Information Sciences, 2012
Sparse microwave imaging is a novel radar framework aiming to bring revolutions to the microwave imaging according to the theory of sparse signal processing. As compressive sensing (CS) is introduced to synthetic aperture radar (SAR) imaging in recent years, the current SAR sparse imaging methods have shown their advantages over the traditional matched
