Laser angle deceptive jamming is one of the effective means for countermeasure the semiactive laser guided weapon,and the false target setting is an important factor for successful laser angle deceptive jamming. In this paper,tactical application analysis of laser angle deceptive jamming was promoted first,and successful conditions of laser angle deceptive jamming were summarized. Then,a new false target setting method for laser angle deceptive jamming was introduced,and the energy spatial distribution of bait was tested. Finally,according to battle scenario designing,the ballistic curves and impact point distribution of laser guided weapon were simulated under laser angle deceptive jamming condition. The results indicate that the laser angle deceptive jamming bait setting method is simple and effective,the bait can implement laser angle deceptive jamming effectively,and the laser guided weapon are departure from the target. The result is helpful to improve the comprehension of the jamming effect evaluation.
