Embodiment Construction

[0032] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] In order to improve the anti-interference capability of the low-delay data link system, the present invention divides the return link frequency resources into M+N channels, where M is the actual number of users, and N is the number of spare channels. During the execution of the mission, the ground equipment detects and analyzes the electromagnetic spectrum conditions in the M+N channels in turn, and selects the channel without interference for communication. The ground equipment sends the confirmed channel control command to the missile-borne equipment through the forward link, and binds the return working channel of the missile-borne data link equipment.

[0034] Such as figure 1As shown, the data link anti-interference method based on autonomous interference detection and real-time channel allocation includes the following st...

Abstract

The invention discloses a data link anti-interference method based on autonomous interference detection and real-time channel allocation. Targeted at a contradiction between low-delay transmission and anti-interference processing in a data link system applied to missile catching and controlling operation, channel interference detection and assessment are performed autonomously through receiving equipment, and available channels are selected autonomously, so that the anti-interference capability of the data link system is enhanced. The receiving equipment performs repeated sampling, statistics and assessment on the channels in sequence according to set frequency sweeping time. Real-time channel availability is given according an interference judgment condition. After available channels are found, working frequencies of a transmitting end and a receiving end are controlled through an instruction in order to rapidly switch to a target channel. Through adoption of the method, interference on the low-delay data link system is avoided on a system level; the equipment anti-interference processing complexity and cost are lowered; and the anti-interference capability of the system is improved remarkably.

Description

technical field [0001] The invention relates to a low-delay data link anti-interference method based on autonomous interference detection and real-time channel allocation, which belongs to the technical field of communication, in particular to the technical field of missile data links. Background technique [0002] The missile data link system, as a bridge between the missile and the ground launch control command system, and between missiles, needs to have the characteristics of high real-time and high availability. Especially in the complex electromagnetic environment of the battlefield, the anti-interference performance of the data link system directly affects the effectiveness of weapons and equipment. [0003] The domestic missile data link system started relatively late, and its wider application is to realize the two-way transmission of guidance images and capture and control commands between the missile and the control station in the image-guided missile system.
