摘要	The cat's eye effect of a space-based Off-axis Three Mirror (OTM) system was analyzed by using the ray tracing method. The effects of image tilt, views of field and the defocus of the OTM system on the echo efficiency and beam divergence angle of cat's eye retro-reflection were given. Then, it pointed out that the image tilt size of the OTM system is a main factor to produce cat's eye echo wave. A threshold method was proposed to actively detect the cat's eye signals, then the influence of diffuse reflection from a target on the detection of cat's eye signals was analyzed by combining the high order cosine scattering mode. The minimum laser pulse energy requirements for 20 km to 120 km detection range under different transmissive beam qualities were given theoretically. The simulation results show that when the beam divergence entire angle is 0.3 mrad, the minimum laser pulse energy requirements at the detection distances of 50 km and 120 km are 0.7 mJ and 3.1 mJ, respectively. Finally, an experiment was carried out to verify the feasibility of the active detection of OTM systems with the cat's eye effects. , 2015, Chinese Academy of Sciences. All right reserved.
