Electronic countermeasure reconnaissance system architecture based on heterogeneous cognitive sensor network

Abstract

The invention discloses an electronic countermeasure reconnaissance system architecture based on a heterogeneous cognitive sensor network. Distributed software-defined reconfigurable electronic reconnaissance equipment performs threat perception on a complex electromagnetic environment; a threat signal feature extraction module performs feature extraction and modeling on the target signal; a target state and behavior characteristic recognition module is used for recognizing a target state and target electromagnetic behavior characteristics; a threat signal sorting module sorts the threat signals according to known threats, unascertained threats and networking threats; a threat autonomous identification module performs threat identification and threat level judgment on the known threat based on a knowledge base; an electronic countermeasure reconnaissance cognitive engine identifies and deduces unascertained threats and networking threats based on an inference engine; and a backbone node reconnaissance resource dynamic management module carries out functional parameter dynamic reconstruction and optimal scheduling on the sensing nodes, so that the threat sensing identification capability of the electronic countermeasure reconnaissance system and the utilization efficiency of reconnaissance resources are improved.

Description
