Simulation in the passive millimeter-wave (MMW) imaging of rough surfaces is an indispensable step in the simulation in passive radiation imaging. The multi-layer brightness temperature tracing method (MBTTM) can be used to simulate the image of a rough surface, which has been proven in our previous work. However, it causes a significant decrease in efficiency of the simulation. To solve this problem, a fast MBTTM is proposed in this paper. In the new method, the uniformly emission method and multi-layer densification method are presented. To validate the correctness of the new algorithm, the comparison of the simulation and measurement results are proposed. These results are in good agreement, which indicates that the fast MBTTM can notably shorten the computing time of the simulation of the roughsurface scene.
