Problems solved by technology

[0003] The existing IFF system has defects such as serious signal crosstalk and confusion, poor confidentiality performance, and easy to be used and deceived. In order to enhance the anti-interference, security and confidentiality of the IFF system, it is necessary to propose an advanced IFF system with encryption mode

Abstract

The invention relates to the technology of novel identification friend or foe, in particular to a multi-channel, anti-interference and anti-aliasing pulse sequence decoding method which is based on an encryption mode and used for advanced identification friend or foe. The multi-channel, efficient, anti-interference and anti-aliasing pulse sequence decoding method aims to solve the problem in the prior art, according to the position interval and tolerance range between standard pulse sequences, the obvious anti-aliasing and anti-interference effect can be achieved on the multi-path phenomenon generated in pulse sequence broadcast in a complex electromagnetic environment and malicious signal interference of foe in modern information countermeasure, the correct decoding rate is greatly improved, and safety and reliability of a system are powerfully guaranteed. Through set basic windows and actual sliding window models, all input pulse sequences and sequences of the sliding window models are compared, pulses meeting conditions are obtained, a final pulse sequence is obtained by selecting related parameters of the amplitude peak value, and the design requirement is met.

Description

technical field [0001] The invention relates to a novel friend-or-foe identification technology, in particular to a multi-channel effective anti-jamming and anti-aliasing pulse sequence decoding method for advanced identification of friend and foe based on encryption mode. Background technique [0002] Identification of friend or foe is one of the important means of military confrontation in the modern information battlefield. It can greatly enhance the accuracy of combat command and control and the coordination between various combat units, significantly speed up the system response speed, and reduce the probability of fratricide. It is especially suitable for Multi-arms combined combat use. With the unprecedented improvement of weapon strike accuracy and the continuous enhancement of destructive power in modern warfare, the military of various countries pays more and more attention to the development of identification friend or foe system. [0003] The existing IFF system...
