Abstract:
The use and safeguard of radar klystron are one of the main links in improving operation quality and reducing the cost in radar station, because the performance of klystron directly affects the quality of radar echo, operating costs and the lifetime of use. It is very important and necessary to use and safeguard the klystron better in the case of Yunnan 6 CINRAD/CC radars’ operations in recent years. For example, in Dehong and Pu’er radars, based on both klystron operation principle and practical experience, the operating performance of klystron is determined by the change of collecting waveform, transmission power and anomalous propagation. Based on years of experience, it is shown that the electron gun of klystron is usually considered vulnerable and easy aging. It should be appropriately increased the klystron electron gun filament current so that the full activation of the filament and the new tube keeping with good vacuum during the initial klystron operational period. It should be slightly lowered filament current during the medium klystron operation period. During later period, it should be increased the filament current to ensure the quality of radar echo because klystron cathode emission capability may be decreased at this period. Based on the above operation initiatives and proposals on klystron, it could extend the use lifetime of klystron without affecting the quality of detection. The method should also be good reference for other CINRAD radars.
