8 June 2012Through-the-wall moving target detection and localization using sparse regularization
In this paper, we consider moving target detection and localization inside enclosed structures for through-the-wall radar
imaging and urban sensing applications. We exploit the fact that the through-the-wall scene is sparse in the Doppler
domain, on account of the presence of a few moving targets in an otherwise stationary background. The sparsity property
is used to achieve efficient joint range-crossrange-Doppler estimation of moving targets inside buildings using
compressive sensing. We establish an appropriate signal model that permits formulation of linear modeling with sensing
matrices, so as to achieve scene reconstruction via sparse regularization. Supporting simulation results show that a
sizable reduction in the data volume is achieved using the proposed approach without a degradation in system
performance.
