Abstract

The invention relates to an interference resource configuration method and device, and relates to the technical field of radar signal processing. The interference resource configuration method comprises the steps of sorting and identifying radar signals detected by each jammer of a cooperative interference system, and carrying out information fusion processing on a sorting and identifying result to obtain radar signals after information fusion processing; performing threat assessment on the radar signals after information fusion processing to obtain a threat assessment result of each radar signal; and determining an interference resource configuration mode in the cooperative interference system according to the threat assessment result of each radar signal so as to interfere with each radar based on the interference resource configuration mode. Through the steps, the cooperative interference effect for radar signals can be improved, the real-time performance is good, the flexibility ishigh, the algorithm is easy to implement, the defects of a previous method are overcome, and the method is particularly suitable for the cooperative interference system.

Description

technical field [0001] The present invention relates to the technical field of radar signal processing, in particular to a method and device for configuring interference resources. Background technique [0002] With the rapid development of radar technology, radar signals have become extremely dense, and the signal density has increased rapidly, and the electronic countermeasure electromagnetic environment has become more and more complex. At the same time, with the development of the modern radar system, the anti-jamming performance of the radar has become more perfect. In many cases, a single jammer cannot effectively interfere with a single radar with excellent performance. If faced with a radar network composed of multiple radars, a single jammer cannot complete the jamming task. Therefore, in the prior art, a technical solution of multiple jammers against multiple radars is proposed. In this technical solution, each jammer works independently. Although the real-time p...
