Abstract

In this paper, a generalized electromagnetic (EM) wave penetrating propagation model is presented to improve the imaging quality for through-the-wall radar with compressed sensing (CS) technique,. Compared with those penetrating propagation models established only in the 2-D space, the proposed model considers the propagation path in the 3-D space to reduce the mismatch error between the observation model used in CS and the physical procedure. The EW wave propagation path is calculated with an analytical expression with some approximation for stand-off sensing, which is computationally efficient for CS imaging. Real data are used to validate the model proposed. It is shown that the CS imaging with the model proposed can yield better performance in locating and clutter suppression.
