Abstract :
This paper focuses on a common but rarely studied interference phenomenon caused by an uneven medium surface in holographic penetrating imaging. This interference has serious effect on the imaging process of concealed targets, especially for the narrow band holographic subsurface radar. Simulations based on the model of uneven medium surface are implemented to illustrate the negative effect. An uneven surface compensation method is proposed to eliminate the reflect waves of uneven surface. Simulation results show the effectiveness of the compensation method.
