- Abstract
In recent years,satellites formation flying and inter-satellite link technology has become a hotspot in the aerospace field. Under this trend, it is necessary to ensure the relative stability of formation configuration and realize inter-satellite cooperation through inter-satellite communication and relative position measurement. Integrating inter-satellite communication and satellite distance measurement into the integrated platform can realize the integration of communication and ranging,reduce the load,and meet the development trend of current satellites. An integrated waveform is designed for the millimeter wave inter)satellite link. At the same time,a series of signal processing technologies are proposed to complete the synchronization and separation of waveforms,so as to realize the integration of inter-satellite communication and ranging. For the influence of separated waveform and power amplifier nonlinearity on communication signal,a signal detection algorithm based on deep learning is used to reduce the bit error rate of communication data. The simulation results verify the feasibility of the designed integrated waveform and signal processing technology in the application of inter-satellite link.
