The damageable effect and corresponding tactics for fighting system under complex electromagnetic environment

From the composing of the complex electromagnetic environment and the time, frequency, spatial, energy, and polarization domain, the damageable effect of fleet information system and fighting system are analyzed, and then we discuss the degradation, invalidation performance of sensitive electric information system for the sake of the complex electromagnetic environment. We also propose some corresponding tactics against the damageable effect of the information system for ship and the whole fleet, such as the token method of e-fight source environment, behavior-model of energy transfer in front-end of sensitive receiver system, new protection rules, information integration method and combined frequency management. All these method can improve the performance of the ship fleet under complex electromagnetic environment.
