A Method of Suppressing Radar Dense False Target Interference

Abstract

The invention relates to a radar interference inhibition method and particularly relates to a radar dense false target interference inhibition method. The radar dens false target interference inhibition method comprises steps of importing orientation video data of an object to be detected which is scanned by the radar, calculating the orientation noise power of the object to be detected to obtain a noise evaluation value, recognizing interference, perceiving the interference environment and positioning the interference source, 3 identifying the interference, performing signal statistic analysis on the radar scanning video data in the interference field, determining whether the dense false object interference exists, 4 inhibiting the interference, adopting the frequency domain filtering technology to perform interference resistance processing on the dense false object interference data, 5 detecting an object, adopting CFAR to process the object data to be detected which has gone through anti-interference inhibition, and 6 performing tracing and track correlation on the object to be detected to finish the tracking of the object. The radar dense false target interference inhibition method can guarantee the normal operation of the radar under the interference of the dense false objects and identifies whether the false objects exist through the characteristic analysis.

Description

technical field [0001] This patent relates to a radar interference suppression method, in particular to a radar dense false target interference suppression method. 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 serious threat to radar wit...

AI Technical Summary

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.
