| Abstract | 微波功率测量是射电天文强度校准的关键环节，本文针对微波功率测量，设计了一种基于Arduino的微波功率测量系统。该系统以Arduino UNO和AD8318对数检波器为核心，设计并编写了Arduino UNO的程序，实现了微波功率测量，并通过串口输出至PC端。通过搭建微波功率计测量系统，使用信号发生器产生5个频率下10个输出功率的测试信号，进行功率测量，实验结果显示功率测量系统能保持±1d Bm的误差范围。还使用了2点法校准在5个频率下对系统做了校准，实验结果显示不同工作频率下测得的斜率和截距会有略微的差别。可通过系统本论文相关的分析研究可为射电天文接收机的功率测量提供参考，尤其对强度校准具备很好的指导作用。 |
| Other Abstract | Microwave power measurement is a key part of radio astronomical intensity calibration. In this paper, an Arduino-based microwave power measurement system is designed for microwave power measurement. The system is based on Arduino UNO and AD8318 logarithmic detector as the core, and the program of Arduino UNO is designed and written to realize microwave power measurement and output to PC through serial port. By building a microwave power meter measurement system, using a signal generator to generate a test signal with 10 output powers at 5 frequencies for power measurement, the experimental results show that the power measurement system can maintain an error range of ±1dBm. Also used the 2-point method of calibration at 5 frequencies to do the calibration of the system, the experimental results show that the slope and intercept measured at different operating frequencies will have a slight difference. The analysis of the system related to this thesis can be used as a reference for power measurement of radio astronomy receivers, especially for intensity calibration with good guidance. |
