Abstract

The present invention discloses an SMRD-based meteor trace track simulator and relates to the field of meteor track test application. The simulator comprises a first interface matcher, a first splitter / combiner, a numerical control attenuator, a second splitter / combiner, a second interface matcher, a first noise generator, a signal controller, a second noise generator and a monitoring unit. Based on the SMRD data developed by radar observation of meteors for several decades, the present invention combines the meteoroid operation rule with meteoric tracks from the aspects of meteor generation, generation and diffusion of available tracks, electrical characteristics of tracks and electromagnetic environment for meteor trace track simulation. This can be close to the application environment and reflect the transmission characteristics of the track more truly. The invention has the characteristics of high integration and simple circuits, is convenient in use, stable and reliable in performance. The simulator is especially suitable for testing and validating the actual link transmission capability through the laboratory environment and can also be used for the joint test and communication capability test of newly developed meteor trace 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...
