Abstract :
Forward-Looking Ground Penetrating Radar (FLGPR) can be used for detecting landmines. The detection process involves generating synthetic aperture radar (SAR) images using the standard backprojection (BP). The BP approach suffers from poor resolution and high sidelobe problems. This paper focuses on enhancing imaging resolution and reducing sidelobes using the Sparse Iterative Covariance-based Estimation (SPICE). A MIMO FLGPR developed by the Army Research Laboratory (ARL) is used for analysis.
