Passive Millimeter-wave Radiation Imaging Simulation of complex three-dimensional Target

In this paper, based on fast ray-tracing method, the passive millimeter-wave (PMMW) radiation images of three-dimensional (3D) target are simulated. Firstly, the PMMW imaging simulation method is introduced. Then, a PMMW radiation simulation example of ship on sea is presented to verify the effectiveness of the simulation method.
