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...
