摘要
通过开展1-40 GHz微波暗室性能自动校准技术研究,研制了低反射8维度空间测试支架,降低了测试装置微波干扰;开发了基于Labview 8.6环境的测试系统控制软件,实现信号调整和收发天线的相对运动;本文就微波暗室自动校准系统静区反射率电平测量不确定度进行了分析和评定。
A 1-40 GHz auto-calibration technique was developed for microwave anechoic chambers,and an octuple space motion frame with low reflection was developed to reduce disturbing microwave signals. The control software of the test system is based on Labview 8. 6 and it can realize signal modulation and antennas relative movement. Analysis and evaluation was made on the measurement uncertainty of the quiet zone reflectivity level in the microwave anechoic chamber.
