Abstract

The invention relates to a radar narrow-band interference identification method based on envelope histogram distribution. Aiming at the defects of fuzziness and subjectivity caused by more dependence on manual judgment and setting on traditional radar interference type confirmation and anti-interference measure selection, the invention provides a method for accurately classifying four typical narrow-band interferences, namely narrow pulse interference, suppressing interference, deception interference and convolution interference. The method comprises the specific steps of echo amplitude envelope construction, constant amplitude histogram distribution statistics, near window fine compensation, adaptive classification and recognition and the like. According to the invention, the automatic selection capability of anti-interference measures is effectively enhanced, and the operational effectiveness of the radar in a complex electromagnetic environment is improved.

Description

technical field

[0001] The invention relates to an interference identification method, which is mainly used in the field of classification and identification of radar interference signals. Background technique

[0002] Accurate and real-time perception of space interference situation in a complex electromagnetic environment is an important prerequisite for optimal selection of countermeasures and refined and hierarchical interference suppression in the game between radar and electronic warfare equipment. With the continuous development of electronic warfare equipment, typical jamming patterns such as narrow pulse jamming, suppressive jamming, deceptive jamming, and convolution have been proposed one after another, posing new challenges to modern radars' ability to perceive the battlefield jamming environment.
