Interference characteristic extraction method based on projection transformation

Abstract

The invention discloses an interference characteristic extraction method based on projection transformation. The interference characteristic extraction method comprises following steps of: 1, calculating radar parameters; 2, interference sensing: sensing interference environment and judging whether interference exists or not; 3, interference positioning: calculating an interference orientation center and the interference strength and positioning an interference source; 4, projection transformation: selecting interference data of an interference strength concentration region, and adopting a projection transformation method to calculate a projection characteristic matrix; 5, interference slope characteristic extraction: carrying out characteristic counting on the projection characteristic matrix, analyzing characteristic distribution in the orientation, and calculating interference slope characteristics; and 6, feeding back the interference slope characteristics to a radar system.

Description

technical field [0001] The invention relates to an interference feature extraction method, in particular to an interference feature extraction method based on projection transformation. Background technique [0002] An important feature of modern military electronic technology is that various weapons and equipment are more and more widely used and depend on radio technology. The display of the power of various weapons and equipment, the monitoring and alerting of theaters, the deployment, contact and control of various arms cooperative operations, etc., all rely more and more on the effectiveness of radar. Therefore, electronic warfare has become another dimension of modern warfare. On the battlefield, suppressive and deceptive active electronic jamming will run through the entire process of warfare, making radars face an increasingly complex electromagnetic environment. [0003] The comprehensive electronic jamming technology developed rapidly in recent years poses a serio...

Problems solved by technology

[0008] (2) The research is not systematic enough

At present, domestic research on new radar anti-jamming methods and new technologies is still relatively isolated, and there is still a big gap in the depth of research;

[0009] (3) There is a gap between test verification and application

Most of the theoretical research results of developed countries have been successfully applied to military equipment, realizing the actual combination of theoretical methods and equipment. Many new domestic theoretical methods have not yet been well integrated with weaponry and equipment.
