Abstract
The present invention discloses a geographic information-based simulation test system for medium-high frequency communication channels, comprising a human-machine interface module, a geographic information processor, a ground wave signal simulation processing module, a sky wave signal simulation processing module, a digital map, an ambient noise generation module, a time generator, and an simulation signal synthesizer. A ground wave transmission signal and a sky wave transmission signal are respectively simulated according to a ground wave transmission path and a sky wave transmission path; and finally, the ground wave simulation signal, the sky wave simulation signal, and the ambient noise signal are synthesized and sent to a medium-high frequency receiver. By means of the geographic information-based simulation test system for medium-high frequency communication channels, the test cost of the medium-high frequency communication system and device can be reduced, the signals that may be actually received by the medium-high frequency receiver at any location in any period of a year can be simulated quickly, thereby greatly increasing the test speed of the medium-high frequency communication system and device.
