Cooperative guidance method based on impact time and angle control

Abstract

Suicide-attack UAVs need to adopt cooperative guidance to simultaneously attack the target from different directions under strong confrontation conditions. Therefore, a cooperative guidance law based on impact time and angle control is proposed. Firstly, an auxiliary phase is introduced to a two-phase guidance law to enhance its time control ability. On this basis, the switching conditions of the two-phase guidance law with an auxiliary phase are modified to simultaneously control the impact time and angle. With the desired impact time and angle taken within their permissible sets, the constraints on the acceleration and field-of-view will be satisfied during the engagement with the proposed algorithms, which can be used to realize cooperative guidance. Finally, the effectiveness of the methodology is verified by numerical simulations.
