摘要：
In this paper, we exploit the hyperparameter-free LIKelihoodbased-Estimation of Sparse parameters (LIKES) method for Through-the-Wall Radar Imaging (TWRI). The Rotational Signal Subspace (RSS) method is utilized to convert the single snapshot data set into the equivalent multiple snapshots, which allows us to apply LIKES to TWRI without loss of array aperture. Experiments on real data show that LIKES can improve the image quality compared to the Back-Projection (BP) and Capon algorithms.
