Abstract: In this paper, the problem of cooperative capture of maneuvering target with incomplete information is studied based on differential games. Firstly, the differential game model and the corresponding differential game cooperative guidance law for cooperative capture with multiple aircrafts are given. Secondly, considering that the acceleration of the target is unknown in the calculation of zero-control miss distance, the model set for multi-model filtering is established, with the possible maneuvers of target being taken into account. Then, estimation of target acceleration is obtained by the interacting multi-modal particle filtering algorithm. Finally, the effectiveness of the proposed estimation method is verified by the simulation scenario, and the target is successfully captured using the presented guidance law with the estimated target acceleration.

Key words: maneuver target, acceleration estimation, differential game, cooperative capture, incomplete information
