| This article tell of design principle and satellite antenna testing instrument by the numbers and give a relatively detailed introduction of antenna testing condition,controlling of antenna platform and testing method of radiation pattern.ln the text ,it is emphasized that the standard of satellite antenna capability.Three problems are resolved in the process of manufacture instrument.The number one is controlling of the antenna platform rotation following the testing requirement strictly.The second is how to deal with testing signals and translate it into digital signals.The last are getting the antenna radiation pattern on the basis of digital signals and drawing the corresponding antenna pattern envelop.Then the main standards of satellite antenna are calculated according to the antenna patlern.ln the course of instrument design, Computer is adhibited to antenna parameter measure as a kind of high-powered information processor in modern time. We make the best of its powerful ability of logic judgement, calculate and information process. Render the measure of antenna to a new level , The process of measure is more automatic and more reliable, the measure of antenna is more precise, the quality is better, the operation is more simple and frank. The text consist of five parts:antenna measure and computer control,the principle of satellite antenna testing instrument,processing testing signals,controlling antenna platform and interface of the instrument. |
