This paper designed an airborne laser fuse detection simulation system to study the boundary values of the main parameters of laser fuzes when targeting"low-slow-small"(LSS)objects.Focusing on a typical LSS unmanned aerial vehicle(UAV)as the interception objective,a laser fuze detection model was constructed based on the engagement scenario between the LSS UAV and the projectile.The simulation system for airborne laser fuse detection was designed,and a simulation example and analysis were conducted to assess the impact on the boundary values of the main parameters when the laser fuze detected"low-slow-small"UAVs.The results indi-cated that the designed simulation system could provide effective theoretical support for the design and develop-ment of airborne laser fuzes.
