Abstract

The invention discloses an SMRD-based meteor trail channel simulator and relates to the field of meteor trail communication application testing. Including the first interface matcher, the first divider / combiner, the digital control attenuator, the second divider / combiner, the second interface matcher, the first noise generator, the signal controller, the second noise generator and the monitor unit. The present invention is based on the SMRD data formed by radar observations of meteors over the past decades, combined with the laws of celestial bodies, and analyzes meteor trails from the aspects of meteor generation, generation and diffusion of trails, electrical characteristics of trails, and electromagnetic environment. The channel is simulated, which can approach the application environment more realistically and reflect the transmission characteristics of the channel. The invention has the characteristics of high degree of integration, simple circuit, convenient use, stable and reliable performance and the like. It is especially suitable for the test and verification of the actual link transmission capability through the laboratory environment, and it can also be used for the joint test and communication capability test of the newly developed meteor trail communication equipment.

Description

technical field [0001] The present invention relates to the field of meteor trail communication application testing, in particular to a meteor trail channel simulator based on sporadic meteor radiation distribution (Sporadic Meteor Radiant Distribution, referred to as SMRD), which is especially suitable for realizing the actual link through the laboratory environment. When the transmission capability is tested and verified, it can also be used for the joint test and communication capability test of the newly developed meteor trail communication equipment. Background technique [0002] Meteor trail communication is a long-distance communication method, and its communication distance can reach thousands of kilometers, and the transmission capacity is related to the geographical location of the site and background noise. In practical applications, in order to select a link with better transmission capacity, it is necessary to conduct long-term field tests at two communication s...
