Embodiment 1

[0040] In the communication confrontation environment, in order to stably evaluate and screen out the generative spoofing jamming signal samples constructed based on GANs in the direct spread system, the present invention proposes a generating and evaluating device for generating spoofing jamming signals. By further improving the expression of the Pearson correlation coefficient, the method alleviates the influence of signal power on the correlation coefficient, so that the low-power direct spread signal participates in the evaluation calculation of the generated signal efficiency and can successfully screen out high-efficiency generated signal samples.

[0041] Such as figure 1 As shown, the main implementation process of the method for evaluating the effectiveness of generative deception interference based on the improved correlation coefficient proposed by the present invention is as follows:

Abstract

The invention relates to the field of communication countermeasure, in particular to a generative deception jamming signal generation evaluation method and device. According to the invention, interference efficiency evaluation is carried out on the pseudo-deception interference signal constructed by the GANs by using the improved correlation coefficient, and the stability of efficiency evaluation of the generated signal sample is remarkably improved. The Pearson's correlation coefficient can reflect the interference efficiency of a generative deception interference signal on a direct spread system to a certain extent, but is greatly influenced by signal power, and will fail under the condition that a real signal with a low signal-to-noise ratio participates in calculation. According to the method, the Pearson's correlation coefficient between the generated signal and the low-power direct spread signal is subjected to telescopic transformation, so that the influence of signal power on the correlation coefficient is effectively reduced. The method provided by the invention is simple in calculation and stable in performance, is helpful for screening high-efficiency generation type deception jamming signals with strong attack force, and has very important practical significance in a confrontation environment.

Description

technical field [0001] The invention relates to the field of communication countermeasures, in particular to a method and device for generating and evaluating a generated deceptive interference signal. Background technique [0002] Direct sequence spread spectrum communication technology is one of the core technologies of satellite communication and mobile communication. It has strong anti-jamming and strong anti-interception capabilities, and has been widely used in both military and civilian fields. In the countermeasure environment, since the suppressive interference is not related to the spread spectrum signal of the direct spread system, the receiving end of the system will suppress most of the interference, so the interference effect is limited. Only insensitive to the spread spectrum gain of the direct spread system, the spoofed jamming that is strongly correlated with the spread spectrum signal can effectively attack the direct spread system. The present invention w...
