Target radar threat degree evaluation method based on knowledge graph

Abstract

The invention discloses an evaluation method for acquiring a target radar threat degree by utilizing a TransE knowledge inference model based on a knowledge graph. Traditional threat level judgment only depends on indexes such as reconnoitred radiation source radar technical parameters and working states, the characteristics of actual combat application are not considered, that is, the propertiesof a platform carried by the radiation source radar and other radiation source radar information on the carrying platform are not considered, therefore the evaluated threat level is not accurate enough. According to the method, the knowledge graph with the radar and the carrying platform as the core is constructed, the TransE inference model is used for mining the hidden relation between the radarand the radar and the hidden relation between the radar and the carrying platform, and the obtained information is comprehensively used for evaluating the threat degree of the target radiation sourceradar more comprehensively and more accurately. According to the method, the problems of incomplete acquired information, incomplete evaluation indexes and the like in the prior art are solved, the evaluation accuracy of the target radar threat degree is improved, and the method has good practicability.

Description

technical field [0001] The invention belongs to the technical field of radar electronic countermeasures, and in particular relates to an evaluation method for obtaining a target radar threat degree based on a knowledge graph and using a TransE knowledge reasoning model. Background technique [0002] Judgment of threat level is an important content in modern radar warning system, especially in the application of real-time warning jamming, for multiple radiation source radars with different threat levels, the best jamming effect can be achieved by implementing jamming measures corresponding to priority levels. The traditional threat level judgment is based on the technical parameters of the radiation source radar, working status and other indicators, estimating its harmful capabilities and combat intentions, and through weighting processing, according to the degree of damage that the radiation source radar may cause to our side, and Consider the characteristics of actual comba...

AI Technical Summary

Problems solved by technology

However, a combat platform is often equipped with multiple radars, and it will be difficult to determine the threat level of the radiation source radar only through the obtained technical parameters and working status of a single radar.
