Technical Field

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

Background

With the continuous expansion and penetration of lunar and deep space exploration activities in China, most of current frequency bands for world communication and information transmission belong to radio frequency bands, radio frequency band resources are more and more intense, and high-speed, general and efficient support services are difficult to provide for spacecraft tasks. At present, the research on the development of laser communication for space communication is imperative. In order to solve the difficult problem of deep space high-speed communication, the main approach is to increase the carrier frequency to the Ka frequency band and to use a laser link. Meanwhile, for satellite and deep space exploration application with limited weight, volume and power consumption, strict requirements are put on the weight, volume and power consumption of the effective load. In order to effectively reduce the volume, weight and power consumption (SWaP) of the communication load, the demands for the satellite platform for the communication load to be high-speed, lightweight, miniaturized, comprehensive and integrated are becoming more and more apparent. 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 of radio frequency communication, a laser communication system and functions becomes a key problem to be solved.

The laser 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 the parts of a common antenna, a tracking system, an electronic unit, a thermal control and the like. The advantages of high transmission rate and high anti-interference capability of laser communication and the characteristics of high channel adaptability of radio frequency communication although the communication rate is low and the radio frequency communication is easy to be interfered are combined, and the two characteristics are cooperatively used: when the channel is allowed, the laser communication is adopted for high-speed transmission, and when the channel condition is reduced and the laser communication cannot be used, the radio frequency communication is adopted for transmission, so that the availability and usability of the communication system are improved.

In the prior art, a Chinese patent with the publication number of CN103762998B introduces a large-view-field co-antenna mixed radio frequency and laser wireless communication device, and mixed communication is realized through a radio frequency laser co-antenna, but a modulation and demodulation module of a radio frequency signal and an optical signal of the device are separated, the integration level of a communication component is low, and the device adopts capturing and tracking of beaconing light, so that the complexity of a tracking system is high; in the second prior art, china patent with publication number CN103873151B introduces a satellite-borne integrated communication system compatible with radio frequency, laser and quantum communication, and provides a satellite-borne integrated communication system capable of simultaneously realizing radio frequency, laser and quantum communication functions, but the system integration level is not high, a radio frequency antenna and an optical antenna are not integrally designed, and the volume, the weight and the power consumption are larger; in the third prior art, chinese patent publication No. CN107317593B describes a dual-link communication receiving system, where hybrid receiving of radio frequency and laser signals can be achieved 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, and the signal processing unit has low integration level and no transmitting link, so that bidirectional communication cannot be achieved; in the fourth prior art, the Chinese patent with publication number of CN107682044B introduces a laser and radio frequency hybrid transmission system, which can realize hybrid communication of laser and radio frequency, but a radio frequency antenna and an optical antenna of the system are also mutually independent structures, so that the integration level of the system is not high, and the satellite-borne and deep space communication application is not facilitated; in the fifth prior art, the Chinese patent with publication number of CN110233665A introduces a radio frequency/laser cooperative rapid capturing, tracking and aligning method, which can realize rapid and high probability capturing, tracking and aligning light beams in a long-distance full airspace, but only realizes radio frequency/laser hybrid capturing, tracking and cannot realize radio frequency/laser hybrid communication.

The above five technologies all realize laser radio frequency integrated communication, but do not thoroughly solve the problems of integration of a laser radio frequency antenna, integration of a tracking system and integration of a signal processing system, and still have the problems of larger volume, weight and power consumption of communication load.
