摘　　要：利用多爆炸成型弹丸(EFP)的特点,设计了圆周分布200个EFP的装药盘形成拦截弹幕,该结构既能满足俯仰拦截,还能够圆周运动以满足对不同方向来袭目标的拦截;在给定的随动误差下,通过来袭目标与拦截区域的投影面积,编写拦截弹幕与目标随机交汇程序,汇总计算交汇概率;结果表明:随动误差控制在0.2°以下以及在来袭目标与拦截弹幕之间夹角α在0°~50°拦截最佳,交汇概率均在70%以上,且至少有3发EFP弹丸击中目标。Using the characteristics of muhiple explosively formed projectile （EFP）, we designed the circumferential distribution of 200 EFP charge form interceptor plate. The structure can not only satisfy the pitch angle of the interceptor, but also be able to circular motion in order to satisfy different direction to intercept targets. In the given random error, the target and intercept area of the target are calculated, to writte the random intersection program, and to calculated the intersection probability. Results show that to control the error below 0.2 ° and the incoming angle between target and interceptor α within the scope of 0° -50° to intercept, we have the best effect. The best convergence probability a~ over 70%, and at least 3 hair EFP projectile hit the target.
