The present invention discloses a multi-channel meteor trail channel simulator, and relates to the transmission environment simulation equipment of meteor trail burst communication channel in the field of communication. The channel simulator comprises a digital control attenuator, a power distribution / synthesis device, a channel simulation unit, a power supply and other components. When in use, the channel simulator is connected in the meteor trail communication channel in series, to simulate the characteristics of the actual meteor trail channel, which comprise the appearance of random burst and the signal intensity of exponential decay; and the channel simulator can be used for simulation testing of various technical indicators of the meteor trail communication channel. The channel simulator also has the advantages of high degree of integration, simple circuit, small size, convenient use, stable and reliable performance, and so on, and is in particular suitable for the meteor trail channel simulator on the occasions of the joint testing of the system, the transmission threshold testing of the equipment, the capacity testing of the network protocol, and so on in the meteor trail communication system network under the condition of the laboratory.
