Abstract
The problem of impact angle constrained distributed cooperative guidance against maneuvering targets with undirected communication topologies is studied. A novel distributed cooperative guidance strategy is proposed to realize simultaneous attack with impact angle constraint. Firstly, the kinematic equations for the engagement are established. According to the engagement equations, the cooperative guidance problem is divided into two units, which include the cooperation of both impact time and impact angle. Secondly, the guidance algorithm is designed separately for simultaneous attack and dealing with the impact angle constraints. The problem is transformed into a consensus problem via disturbance compensation and feedback linearization technique. The convergence of the guidance algorithm is proven by using the consensus theory. Finally, numerical simulations are presented to verify the effectiveness of the proposed cooperative guidance law.

Summary
Cooperative guidance of multiple unmanned aerial vehicles (multi-UAVs) has been an attractive research area recently. The second way is cooperative guidance, in which UAVs communicate with neighbors to attack targets at a specific time without setting a fixed impact time. A distributed time cooperative guidance law is designed by the second-order consensus theory. Wang and Tan [15] designed a cooperative guidance law, which can make the remaining flight time of multiple UAVs converge to consensus in a fixed-time. In [34], a distributed cooperative guidance law is designed to realize simultaneous attack. The advantages of our research can be summarized as follows: (1) The cooperative guidance law proposed in this paper can apply to a maneuvering target. (3) The cooperative guidance law we proposed can achieve simultaneously attack and the coordination between impact angles. The strategy proposed in this paper is distributed and does not need to set a specific attack angle, which will help to reduce energy consumption
