A geometry model with periodicity and randomicity was put forward to analyze the microwave diffraction behavior of the flocculent screen. The peculiarity of the model is that, on the one hand, the model treats the flocculent screen as a periodic structure to facilitate digital calculation; on the other hand, the randomicity of the screen is endowed to the periodic cell. The periodic cell of the model consisted of vast scatters, and the randomicity of the structure was formed by the distribution of the scatters in position and direction. Based on this model, the diffraction behavior of the flocculent screen was calculated by FDTD method. Results indicate that the flocculent structure improves the camouflage effectiveness of the screen by dispersing the miacrowave energy. Source
