Based on minimizing the enclosed area around the target of multi-attackers, two novel guidance laws are created to address the issue of cooperative encirclement and simultaneous attack. The only requirement for the multi-attacker communication network is that it should contain a directed spanning tree, and does not require all attackers to observe the target information, where at least one can observe the target. To reduce the remaining relative distances between the target and attackers simultaneously, and to make the overload in direction perpendicular to the line of sight converge to zero, the multiple-attackers-single-target problem is effectively solved and can avoid collisions among attackers as well as difficulties in estimation of remaining time. Simulation results confirmed the effectiveness of the proposed guidance laws.

基于缩小周边区域的多无人机协同攻击运动目标分布式制导律设计

在最小化多人攻击目标周围的封闭区域的基础上，创建了两种新颖的制导律来解决协同包围和同时攻击的问题。对多攻击者通信网络的唯一要求是它应该包含一棵有向生成树，并且不需要所有攻击者都观察到目标信息，其中至少有一个可以观察到目标。同时减少目标与攻击者之间的剩余相对距离，并使垂直于视线方向的过载收敛为零，有效解决了多攻击者-单目标问题，同时避免了攻击者之间的碰撞由于难以估计剩余时间。仿真结果证实了所提出的制导律的有效性。
