Method for intelligently sensing unascertained threat electromagnetic behavior by cognitive sensor network

Abstract

The invention discloses a method for intelligently sensing an unascertained threat electromagnetic behavior by a cognitive sensor network. The method comprises the steps: performing feature extractionon a target through a threat signal feature extraction module and establishing a target state and behavior feature model; enabling a threat signal sorting module to carry out main sorting on pre-sorted targets based on target states and behavior features; enabling the target state and behavior feature identification module to perform known threat target state identification and target electromagnetic behavior feature identification based on a threat signal sorting result; enabling an electronic countermeasure reconnaissance cognitive engine inference engine to perform target state and electromagnetic behavior feature inference identification on unascertained novel threats and networking threats based on an information game mathematical model, and outputting identification information suchas a target type, a working state and identification confidence. According to the method provided by the invention, the state information of the observable signal can be more systematically used foridentifying an unascertained threat state, the coupling influence of a complex electromagnetic environment and an adaptive threat on electronic countermeasure reconnaissance is reduced, and the electronic countermeasure reconnaissance efficiency is improved.

Problems solved by technology

At present, technologies such as radar anti-jamming and low-interception are developing rapidly, and new equipment such as adaptive radar systems are emerging and deployed. The electromagnetic environment of the battlefield is becoming increasingly complex. Electronic countermeasures and reconnaissance systems can quickly intercept, sort, and identify threats from a large number of complex signals. Targets are becoming more and more difficult, especially the effective perception of enemy radar signals with new, unknown or uncertain waveforms and behaviors has become a huge challenge, seriously restricting the combat effectiveness of electronic countermeasures and reconnaissance systems

At the same time, in the process of electronic countermeasures, the electronic countermeasures and reconnaissance system is limited by tactical use and technical conditions. In the process of confrontation, it is difficult to obtain a large amount of effective prior knowledge for such unknown threats through online detection and acquisition of threat signal samples
