Several sorts of laser jamming technology, most commonly used in the current war, and its current situation and the development trend are summarized firstly, then the performance and characteristics of laser jamming technology are introduced, and the function, jamming theory and key techniques of laser jamming of angle deception are discussed purposefully. Based on the above analysis, a kind of hardware-in-the-loop (HWIL) simulation evaluation method, which is the foundation to jamming effectiveness for laser jamming of angle deception equipment against laser guidance weapon, is proposed and the function, form and main problems existing in this system are analyzed. Finally, the development of test theory of laser jamming with angle deception equipment in shooting range is pointed out.
