Embodiment 1

[0040] In the communication confrontation environment, in order to stably evaluate and screen out the generative deception jamming signal samples constructed based on GANs in the direct expansion system, the present invention proposes a generative deception jamming signal generation and evaluation device. 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 can also successfully screen out the high-efficiency generated signal samples when participating in the evaluation calculation of the generated signal.

[0041] like figure 1 As shown, the main implementation process of the generative spoofing and jamming effectiveness evaluation method based on the improved correlation coefficient proposed by the present invention is as follows:

Abstract

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. The present invention proposes to use the improved correlation coefficient to evaluate the jamming effectiveness of pseudo-spoofing jamming signals constructed by Generative Adversarial Networks (GANs), which significantly improves the stability of evaluating the effectiveness of generated signal samples. The Pearson correlation coefficient can reflect the jamming effectiveness of the generative spoofing jamming signal to the DS system to a certain extent, but it is greatly affected by the signal power, and it will be invalid when the real signal with low SNR participates in the calculation. The invention effectively reduces the influence of signal power on the size of the correlation coefficient by stretching and transforming the Pearson correlation coefficient between the generated signal and the low-power direct spread signal. Moreover, the method proposed by the present invention is simple in calculation and stable in performance, and helps to screen out high-efficiency generative deception jamming signals with strong attack power, and has very important practical significance in confrontation environments.

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 generative spoofing 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-interference and strong anti-interception capabilities, and has been widely used in both military and civilian fields. In the confrontation environment, because the suppression interference is not related to the spread spectrum signal of the direct spread system, the receiver end of the system will suppress most of the interference, so the interference effect is limited. Only the spread spectrum gain of the direct spread system is not sensitive, and the deceptive interference which is strongly related to the spread spectrum signal can effectively attack the direct spread system. The prese...
