Abstract

The present invention provides a cognition-based communication, interference and anti-interference integrated control method. According to the method, signal power, frequency hopping pattern, modulation and identification parameter and coding and identification parameter information is acquired through analyzing cognition. With the method of the invention adopted, the reliability and anti-interference ability of the army force in our country can be improved to the greatest extent; targeted confounding interference messages can be sent according to priori knowledge so as to perform accurate deceptive interference on enemies; and the army force can obtain information countermeasure advantages in a strong confrontation environment at the tail end of a battlefield.

Description

technical field [0001] The invention relates to the technical field of communication countermeasure information system application. Background technique [0002] Due to the strong confrontation environment at the end of the battlefield, our combat platforms and communication systems are directly exposed to enemy firepower and electromagnetic attacks, which seriously threatens the establishment of battlefield information advantages and is related to the victory or defeat of the war. In order to ensure the real-time distribution and sharing of tactical information, as well as the coordinated work of various combat units, and maximize the combat effectiveness of the system, it is necessary to effectively improve the communication, interference and anti-jamming performance in the strong confrontation environment at the end of the battlefield, and form a strategy for confronting powerful enemies deterrent capability. [0003] In order to ensure reliable communication between our...
