Abstract:

In the target-attacker-defenders (TADs) system, the defenders protect the target (aircraft) and reduces the risk of failed interception with a single defender by heterogeneous synergy between the defenders and the target as well as the homogeneous synergy among the defenders. The cooperative active defense model of TADs system in the planar scenario is studied, and a two-layer guidance strategy of target-defender's synergy and defenders group's synergy is adopted. In terms of target-defender's synergy, the leading defender and the target aircraft carry out heterogeneous synergy, considering the maneuverability constraints of the target aircraft and the leading defender, using the cooperative line of sight guidance (CLOSG) law to obtain the guidance commands for the target aircraft and the leading defender respectively; in terms of the defenders group's synergy, a distributed model predictive control (DMPC) based algorithm is designed to achieve simultaneous arrival and interception for the attacker by the following defenders group and the leading defender, considering the single defender's computational capability constraint, interception time constraint and acceleration constraint. Simulation results show that the multi-defenders cooperative and simultaneous interception guidance algorithm can realize the heterogeneous cooperative active defense for target and defenders'group in the TADs system, and realize the simultaneous interception for the defenders to reduce the risk of failed interception with a single defender.

Key words: cooperative active defense, heterogeneous cooperation, target-attacker-defenders (TADs) system, cooperative line of sight guidance (CLOSG), distributed model predictive control (DMPC), simultaneous interception
