Embodiment Construction

[0023] The embodiment of the present invention is divided into two kinds of stand-alone use and multi-machine interconnection, respectively as Figure 4 with Figure 5 shown. The stand-alone mode is used to simulate the channel characteristics of a star network composed of a master station and up to 16 slave stations. Such as Figure 4 As shown, the A, B1 to B4 signal interfaces of the present invention are respectively connected to the radio frequency transmission and radio frequency reception interfaces of the master station, the C interface is connected to the channel switching control port of the master station, and D1 to D16 are connected to the radio frequency transceiver interfaces of the slave station.

[0024] refer to figure 1 , the present invention includes first to fifth front-end matching attenuation units 1-1 to 1-5, multiplex switch 2, first to fourth power distribution and synthesis units 3-1 to 3-4, first to fourth branch Road combination units 4-1 to 4-4...

Abstract

The invention discloses a novel multichannel meteoric trail channel simulator, which is a simulation device of a multichannel meteoric burst communication channel transmission environment in the field of communication. The novel multichannel meteoric trail channel simulator is composed of a multiplexer switch, a power distribution synthesis unit, a splitter and combiner unit, a numerical control attenuator, a control unit, a communication interface unit, a channel switching interface unit, a channel simulation processing unit, a storage unit, a power supply and other components, and is serially connected in devices of a meteoric trail communication system to simulate the influence of an actual meteoric trail channel on a signal, so as to test and check the performance indexes, link performance, networking functions and the like on newly researched meteoric trail communication devices in a laboratory environment. The novel multichannel meteoric trail channel simulator disclosed by the invention further has the advantages of high integration degree, small volume, convenient use, stable performance and the like.

Description

technical field [0001] The present invention relates to a meteor trail channel simulator, especially a new type of equipment that can test and inspect newly developed meteor trail communication equipment in terms of performance indicators, link performance, and networking functions in a laboratory environment. A dedicated platform for simulation training and performance testing of meteor trail communication equipment. The invention belongs to the technical field of meteor trail communication test and inspection. Background technique [0002] Meteor trail communication is a long-distance trans-horizon communication method. After the meteor trail communication equipment is developed, it is impossible to complete all performance and functional index tests in the laboratory environment, especially the networking function, which can only be tested through field tests. The inspection needs to find two test points thousands of kilometers apart, and it can only be completed after s...
