【摘要】 抛物面天线在通讯、遥感、气象观测、天文观测等领域得到广泛的应用,抛物面天线的表面精度对微波通信和观测的效率起着关键作用,本文基于V-STARTS摄影测量软件,在天线反射面上粘贴测量标志,通过摄影来测量天线表面曲线并建立起三维模型,这种方法简化并缩短了测量过程,降低了人为误差对测量精度的影响,有效的提高天线测量的精度和效率.更多还原

【Abstract】 Paraboloid type antenna is widely used in microwave communication,telemetry,remote sensing and radio astronomy.The surface accuracy of antenna is directly related to the efficiency of any communication system.In this paper,the V-STARS photogramety software is used to reconstruct the 3 dimensional model of antenna,the coordination data of target on the antenna is given to calculate the accuracy of surface.The benefit of this test method is all tests can be done automatically;no personal observation error is included during testing,which can improve the test accuracy and efficiency.更多还原
