Description

Resource-saving laser radio frequency integrated communication load

Technical Field

The invention relates to the technical field of electricity, in particular to a resource-saving laser and radio frequency integrated communication load.

Background

With the continuous expansion and deepening of lunar and deep space exploration activities in China, most of the frequency bands used for world communication and information transmission currently belong to radio frequency bands, radio frequency band resources are more and more strained, and high-speed, universal and efficient support services are difficult to provide for spacecraft tasks. At present, the research of developing laser communication by space communication is imperative. In order to solve the problem of deep space high-speed communication, the main approaches are to increase the carrier frequency to the Ka frequency band and adopt a laser link. Meanwhile, for the application of weight, volume and power consumption limited satellites and deep space exploration, strict requirements are provided for the weight, the volume and the power consumption of the effective load. In order to effectively reduce the volume, weight and power consumption (SWaP) of the communication load, the demands of the satellite platform for high-speed, light-weight, small-sized, integrated and integrated communication load are increasingly obvious. Therefore, integrating the radio frequency communication load and the laser communication load into an integrated communication load, realizing automatic switching of two modes of laser communication and radio frequency communication, and realizing integration and unification of the radio frequency communication, the laser communication system and functions become key problems which need to be solved urgently.

The laser and radio frequency integrated communication is a communication mode for integrating laser communication and radio frequency communication, and the volume, weight and power consumption of a communication load are effectively reduced by integrating parts such as a common antenna, a tracking system, an electronic unit, a thermal control and the like. The advantages of high transmission rate and strong anti-interference capability of laser communication and the characteristics of low communication rate and easy interference but strong channel adaptability of radio frequency communication are combined, and the two are used in a cooperative way: when the channel is allowed, the laser communication is adopted for high-speed transmission, and when the channel condition is reduced, the laser communication cannot be used, the radio frequency communication is adopted for transmission, so that the communication rate and the availability of the communication system are improved.

In the prior art, chinese patent with publication number CN103762998B introduces a large-view-field common-antenna hybrid radio frequency and laser wireless communication device, which realizes hybrid communication through a radio frequency laser common antenna, but the modulation and demodulation modules of radio frequency signals and optical signals are separated, the integration level of communication components is low, and the acquisition and tracking of beacon light are adopted, so the complexity of a tracking system is high; in the second prior art, chinese patent publication No. CN103873151B introduces a satellite-borne integrated communication system compatible with radio frequency, laser and quantum communication, and provides a satellite-borne communication integrated system capable of simultaneously implementing radio frequency, laser and quantum communication functions, but the system integration level is not high, the radio frequency antenna and the optical antenna are not integrally designed, and the volume, weight and power consumption are large; in the third prior art, chinese patent publication No. CN107317593B introduces a dual-link communication receiving system, which can realize mixed reception of radio frequency and laser signals by integrating a radio frequency link and a laser link receiving system, but the radio frequency receiving antenna and the laser receiving antenna of the system adopt separate structures, the integration level of a signal processing unit is low, and no transmitting link exists, so that bidirectional communication cannot be realized; in the prior art, a chinese patent with publication number CN107682044B introduces a laser and radio frequency hybrid transmission system, which can realize hybrid communication of laser and radio frequency, but the radio frequency antenna and the optical antenna of the system are also mutually independent structures, and the system integration level is not high, which is not beneficial to satellite-borne and deep space communication applications; in the fifth prior art, chinese patent publication No. CN110233665A introduces a radio frequency/laser cooperative fast capturing, tracking and aligning method, which can realize fast high-probability capturing, tracking and aligning of beams in a long-distance full airspace, but the method only realizes radio frequency/laser mixed capturing and tracking, and cannot realize radio frequency/laser mixed communication.

Although the above five technologies all realize laser and radio frequency integrated communication, the problems of integration of the laser and radio frequency antenna, integration of the tracking system and integration of the signal processing system are not completely solved, and the problems of large volume, heavy weight and large power consumption of communication load still exist.
