| 摘 要： | 就上海佘山25 m抛物面天线上进行的相位相关法微波全息测量及其测量结果做了一定阐述。文章首先简要提到了微波全息测量技术在国内外的发展情况以及理论依据,其次介绍了我们所建立的测量系统的组成,重点讨论了基于窄带信号测量工作的有效性和准确性,采用自校准的数据处理手段,对测量误差做了估计和实际测试。当前我们已经取得了0.14 mm的测量精度(极限误差为0.2 mm),并分析了影响测量精度的各项因素。

| Abstract: | The phase correlation based microwave holography measurement on Shanghai 25 m parabolic antenna is described in this paper.At first,the development of the microwave holography and the theory are mentioned.Then the measurement system that we built is introduced.The efficient and accurate measurement based on narrow band are addressed in detail.The measure accuracy is evaluated by self calibration and also tested actually.We have got the accuracy 0.14 mm at present(limit error is 0.2 mm).The aspects that effe... |
