In this letter, we study the subwavelength imaging of sparse broadband sources inside a disordered medium by processing the data acquired by a single antenna. A mathematical model has been developed for solving such a problem based on the idea of sparse reconstruction. We show that the strongly disordered medium can serve as an efficient apparatus for compressive measurement, which shifts the complexity of devising compressive sensing (CS) hardware from the design, fabrication, and electronic control to a simple and single-calibration procedure. The proposed method and associated results can find applications in several imaging disciplines, such as optics, terahertz (THz), RF or ultrasound imaging.
