Active detection technique based on “cat's eye effect” is an effective means of interference to implement strong laser jamming against drone photoelectric reconnaissance systems. According to the “cat's eye” return characteristics of the photoelectric reconnaissance target, the echo intensity model is established under difference conditions. Simulation analysis is carried out for a typical target in different reflectivity, different laser powers, and different laser divergence angles. The result shows that the simulation results are in accordance with the theoretical model. The conclusions can be used to guide the system design of high-altitude, strong laser jamming system based on active laser detection technique in the future.
