Based on the theory for laser jamming of angle deception, the design of the hardware in the loop simulation system, which had the hardware of its laser jamming of angle deception, was presented. The simulation test circumstances were constructed, which includes the simulation of war and the relative motion between missile and the laser jamming of angle deception, the system is the complement of the wild test, at the same time, which is the foundation to jamming effectiveness valuation of the laser jamming of angle deception equipment against the laser guidance weapon.
