针对高速机动目标的逆轨协同围捕方法

A cooperative encirclement interception method based on virtual aiming points is proposed for intercepting the high-speed maneuvering targets in near-space in three-dimensional scenarios. A calculation method for the ideal interception time of interceptor groups is derived by analyzing the maneuvering envelope of target and considering the guidance characteristics of the interceptors. Thus,the problem of intercepting the high-speed maneuvering targets is transformed into a problem of hitting a specific point on a fixed spatial plane at a predetermined time and angle. Based on the ideal interception time and angle of attack,the virtual aiming points are selected in space to guide the interceptors,ensuring that the impact angles meet the head-on interception conditions,thereby reducing the requirement for the speed of interceptor. The interception tests are conducted on two typical C-type and S-type maneuvering targets through numerical simulation. The results demonstrate that the proposed method is used to successfully intercept C-type and S-type maneuvering targets with different maneuvering intensities, achieve a minimum group miss distance of less than 3 meters,and enable the impact angle meet the requirements of head-on interception angle.
