Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution, and provides detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.

[0054] Such as figure 1 As shown, the MFSK of the embodiment of the present invention is disguised as the anti-interception method of the frequency hopping system comprising the following steps:

[0055] Step S101, the information sending end XORs the coded and interleaved real information with the chaotic information to generate a random frequency hopping sequence, and then generates a frequency hopping pattern through the control of the instruction decoder and frequency synthesizer, thereby hiding the real information in the hopping sequence. The pseudo code part of the frequency system; the specific process is as follows f...

Abstract

The invention discloses an anti-interception method for camouflaging MFSK as a frequency hopping system. Based on an anti-interception performance of the prior frequency hopping system, through combination of a chaos secure communication theory, a general MFSK system is modulated by chaos codes, and then is camouflaged as the random frequency hopping system, which may play a role of confusing the enemy for frequency hopping interception or interference. Our staff only need to detect the frequency point mode to obtain real and effective information. The irreversibility of the chaos codes guarantees the non-interception capacity of real signals. Thus the anti-interception method for camouflaging MFSK as the frequency hopping system is simple and effective; and the direct confrontation can be avoided. Compared with the common anti-interception technology, the anti-interception method of the invention has the better anti-interception performance and anti-tracking interference performance.

Description

technical field [0001] The invention relates to the technical field of measurement and control communication, in particular to an anti-interception method for disguising MFSK as a frequency hopping system. Background technique [0002] With the continuous development of the aerospace industry, the confidentiality, reliability and anti-theft of key data such as aerospace telemetry, remote control, external testing, and shooting range experiments are crucial to national security. For the measurement and control communication system, enemy information detection will seriously threaten the launch and flight safety of various aircraft, spacecraft, and strategic projectors. The anti-interception technology is mainly to ensure information security. Even if the enemy knows that our side is communicating, it cannot grasp the content of our communication. Therefore, the special status of measurement and control signals in space missions and the importance of space communication secur...
