Problems solved by technology
[0002] Active spoofing jamming, especially active angle spoofing jamming, is currently a form of jamming that seriously threatens radio frequency detection systems. Interference signals, increase the distance, speed, angle interference modulation type, deceive the radio frequency detection system to measure the angle of the target, make the detection system's positioning result of the target deviate from the real detection target, and cause target detection failure
[0003] At the same time, the current anti-active angle spoofing methods generally only use time domain information, frequency domain information or other characteristic information, the processing dimension is single, and the characteristics of continuous motion state are ignored, and the target self-correlation information and target interference inter-correlation information are not effectively used. As a result, the anti-interference ability is greatly reduced, and the target detection is seriously deviated.

The embodiment of the invention provides an active angle deception jamming confrontation method and device and electronic equipment. The method comprises the following steps: extracting multi-dimensional features by using echo information to complete target and interference identification; target position information is obtained according to the multi-dimensional features, and whole-process detection of the target is achieved; interference elimination is completed according to the space target position information of the target signal and the interference signal, and stable target tracking is achieved. In this way, the effective detection capability of the radio frequency detector on the target signal under the condition of active angle deception jamming can be effectively improved.
Description
technical field [0001] The present disclosure relates to the field of radar, and in particular, to the field of deception jamming technology. Background technique [0002] Active spoofing jamming, especially active angle spoofing jamming, is a form of jamming that seriously threatens the RF detection system. Interfere with the signal, increase the distance, speed, and angle of the interference modulation type, deceive the radio frequency detection system to measure the angle of the target, so that the detection system's positioning result of the target deviates from the real detection target, resulting in the failure of target detection. [0003] At the same time, the current anti-active angle spoofing methods generally only use time domain information, frequency domain information or other feature information. As a result, the ability to resist interference is greatly reduced, and the target detection is seriously deviated. SUMMARY OF THE INVENTION [0004] The present ...
