Abstract

The invention belongs to the technical field of space communication, and discloses a method for realizing navigation and communication information fusion based on multiple characteristic signals. The method comprises the following steps: acquiring information to be transmitted; fusing the information to be transmitted to obtain fused information; modulating a characteristic signal according to the fusion information, wherein the characteristic signal is an X-ray characteristic energy spectrum signal; emitting an X-ray characteristic energy spectrum signal; receiving an X-ray characteristic energy spectrum signal; discriminating the received X-ray characteristic energy spectrum signal; and separating and extracting the X-ray characteristic energy spectrum signal. Compared with a traditional method of modulating '0' and '1' signals based on intensity or existence of signals, fusion communication of the two kinds of signals is achieved under the condition that the power of communication equipment is not increased, the problems that in the prior art, the communication efficiency is low and the bandwidth is narrow are solved, fusion of more information can be achieved by increasing the types of X-ray characteristic energy spectrums, and the communication efficiency is improved. The bandwidth of a space channel is greatly expanded, and the use efficiency of a space link is improved.

Description

technical field [0001] The invention belongs to the technical field of space communication, and in particular relates to a method for realizing fusion of navigation and communication information based on various characteristic signals. Background technique [0002] The idea of ​​using X-rays for communication was originally proposed by Dr. Keith Gendreau of NASA's Goddard Space Flight Center and is an emerging communication technology. X-rays have the characteristics of high energy, almost no attenuation in vacuum, high orientation and strong anti-interference ability, and have the potential to be suitable for long-distance communication in deep space in the future. At the same time, X-rays can penetrate the electromagnetic shielding environment, which can be applied to the communication and navigation tasks of hypersonic vehicle communication and satellite return module in the black barrier area. [0003] The X-ray communication scheme of the National Aeronautics and Space...
