Problems solved by technology

[0003] At present, the channel modeling methods for the open environment are all analyzed based on the simplified two-path model of direct path + reflection path. The two-path model is established by measuring the line-of-sight propagation and reflection propagation between the transmitting end and the receiving end. However, this model is less effective in practical applications

Abstract

The invention discloses a channel modeling method and device in an open environment. The method includes determining environmental parameters affecting channel transmission in the current open environment. The environmental parameters at least include: surface terrain characteristic parameters; Known information, wherein, the known information of the transmitting end and the receiving end includes: the geographical location of the transmitting end and the receiving end, the relevant indicators of the transmitting and receiving antennas, and the relevant characteristics of radio waves; according to the known information of the transmitting end and the transmitting end and the receiving end Information, determine the propagation mode of radio waves, and calculate the relevant parameters of the determined radio wave propagation mode; based on the relevant parameters of the determined radio wave propagation mode, construct the channel model of the open area, in the channel model thus established Considering the influence of the propagation mode caused by the surface terrain on the channel transmission, the effectiveness of the channel model is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless channel modeling, and more specifically relates to a channel modeling method and device in an open environment. Background technique [0002] In the process of collecting information on the open environment, drones and other aircraft are often used to transmit the surveyed data to the ground-mounted base station through the space-ground channel, and the ground-mounted base station sends the received data back to the ground through the ground channel. It is transmitted to the information center control station for analysis and processing. In order to accurately evaluate the channel transmission performance in an open environment, it is necessary to establish a channel model in an open environment. [0003] At present, the channel modeling methods for the open environment are all analyzed based on the simplified two-path model of direct path + reflection path. The two-path model is establis...
