查询词典 satellite communications

In order to improve the inspection technologies of satellite interference, 5 kinds of technologies of satellite interference and integrated judgement-spectrum analysis, helix inspection, PID, S/N and signal vector were put forward. The automatic inspection system of interference of satellite TV has been built according to these inspected technologies and technology of network. The system adopts comparison of spectrum template, calibration of beaconing, mode identification, telemetering pick-up technology and improve the inspection technology of satellite interference. The alarm limits haw been defined through a lot of emulational tests, so that the system become feasible. The system has a good effect and makes up the blank of inspection technologies of interference in our country to some extent.
