- W4309083981 abstract "Laser communication and distance measurement integration technology is an important development direction of space laser technology, and an important way to realize the future integration of space-earth navigation and communication network. In order to break through higher ranging accuracy, make full use of the space laser link, and realize the integration of high-precision laser communication ranging, this paper analyzes the two ranging methods based on space laser communication link technology: symbol synchronization ranging and carrier phase ranging, proposed a Kalman fusion algorithm to combine these two methods. The technology is modeled, analyzed and simulated. The simulation results show that this method effectively combines the accuracy of symbol synchronization ranging and the high stability of carrier phase ranging. In order to further improve the high dynamic adaptability of the algorithm, the algorithm is analyzed and the corresponding parameters are improved. The results show that the improved algorithm can adapt to the characteristics of space links. The method proposed in this paper makes full use of the carrier characteristics of the space laser link and the communication demodulation technology, and improves the system integration while obtaining higher ranging accuracy, which is of great significance for the design of multifunctional light and small laser terminals." @default.
