本文研究一种偏差模式的推导,这是用以提高ALCOR雷达(天线直径为40英尺)指向精度的。研究的目的是使雷达的指向精度达到50微弧度。在推导偏差模式时,应用了实时测量,结构分析、校准测量、回归等方法;并且讨论了有选择地组合各种方法的综合办法。 俯仰结构和轭架结构的结构分析是分别进行的,俯仰结构由于尺寸过大和各部件之间相互牵扯,所以一个部件一个部件地进行分析。
This article studies derivation of a deviation pattern that is used to improve the pointing accuracy of an ALCOR radar with an antenna diameter of 40 feet. The purpose of the study is to make the pointing accuracy of the radar reach 50 micro-radians. In deriving the deviation pattern, real-time measurements, structural analysis, calibration measurements, regression and other methods are applied; and an integrated approach of selectively combining various methods is discussed. Pitch structure and yoke structure of the structure analysis is carried out separately, the pitch structure due to the size is too large and the various components involved in each other, so a component of a component analysis.
