【Abstract】 Based on the jamming principle of laser-angle-deception,a testing system of hardware-in-the-loop was put forward.Its constitution and working steps were described as well.Using laser seeker,jamming laser,and laser designator,the simulation system were built to simulate the attacking process of laser-guided weapon in approaching real counter environment.Other units of the semi-active laser-guided weapon were simulated by digital simulation.In the hardware-in-the-loop(HWIL) system,laser seeker was mounted on a three-axis flight motion simulator,which simulated the missile attitude and provided a real flight circumstance for the seeker.Key technologies were discussed,including real-time simulation technology,sight-line simulation technology,beam transforming and controlling technology,design of large-area diffuse screen,stray light suppressing technology,and error analysis method for HWIL system.The HWIL technology has been successfully applied,and the jamming effect can be tested and evaluated precisely.更多还原
