Abstract
When through-the-wall ultra-wideband (UWB) synthetic aperture radar (SAR) is applied to imaging, the interference of multipath spreading between targets will introduce ghosts into the SAR image. This paper proposes a hidden Markov model (HMM)-based method for suppressing ghosts in the SAR images. Simulations show that the method proposed can improve the peak value ratio of real targets to ghosts by about 15 dB.
