Abstract: The essence of battle is the process of combat energy storage, perception, transfer and transformation, and the combat energy perception is the logical starting point of combat energy loop, playing a key role in the initiation and operation of the combat energy loop. In order to achieve the match between the equipment and the target, the environment through behavior driving, for realizing the optimization of combat energy perception under the constraint of total combat energy, a combat energy perception equation driven by behavior is proposed. First, the combat behavior spectrum and the combat energy loop are defined, and the relationship between the objects is explicated. Second, the characteristics of combat behavior are analyzed, the formal expression is defined, and a construction method of combat behavior spectrum is proposed. Third, the combat energy perception equation is constructed based on behavior driving, and used for combat energy optimization control. Finally, an example is carried out for validating the proposed method which could provide technical support for the optimization of operational application.
