Abstract

The invention discloses a non-stationary channel simulation method and a non-stationary channel simulation system based on a flight simulation platform. The method comprises the following steps: S1, acquiring flight state information of the position, the altitude, the speed and the attitude of a receiving and transmitting end; s2, selecting a propagation model according to the height of the transmitting and receiving end, determining the boundary of a channel model through the latitude and longitude of the transmitting and receiving end, the height information and channel parameters needing to be simulated in the flight process, selecting different channel models, and then calculating the transmission path loss of a large-scale channel model according to the channel models; s3, performing small-scale modeling by adopting an ellipsoid geometric model according to the flight state information in the step S1, obtaining a Doppler power spectrum, and further obtaining a scattering function of a channel; and S4, inputting the transmission path loss of the large-scale channel model obtained in the step S2 and the scattering function obtained in the step S3 into a channel simulation unit for channel mode. The method overcomes the defects of few actual measurement test opportunities, high cost and the like of the aeronautical communication equipment.

Description

technical field [0001] The present invention relates to the technical field of channel simulation, and more specifically, to a non-stationary channel simulation method and system based on a flight simulation platform. Background technique [0002] The traditional aeronautical telecommunication network (Aeronautical Telecommunication Network, ATN) is a ground-centered communication method, which does not allow direct communication between aircraft. In areas without base station coverage, aircraft communication can only rely on satellites. The high cost of communication makes it difficult for many network applications (such as Internet access, black box data transmission, etc.) to be used on a large scale in the civil aviation field. In addition, in the next two decades, the low-altitude open policy will be gradually implemented in countries around the world, and the flying activities of small and medium-sized general-purpose aircraft in low-altitude airspace will surge. Howe...
