We have proposed digitally controlled millimeter-wave interferometer for precise density distribution measurement. Firstly, we have developed the antenna, that can scan the probe beam in the azimuth plane. It was confirmed that the developed antenna has an ability to scan its beam injection angle within 25 degree by changing the input frequency from 70 to 78 GHz. The proposed interferometer was developed with the antenna, and applied to the dielectric plate for validation of the interferometer performance. As a result of the validation, the interferometer could clearly detect the cross sectional shape of the plate, as well as its thickness.

我们提出了一种用于精确测量密度分布的数控毫米波干涉仪。首先，我们研制了一种可以在方位平面内扫描探测波束的天线。实验结果表明，该天线在70 ~ 78 GHz的输入频率范围内，波束注入角扫描范围在25 °以内。提出的干涉仪与天线一起开发，并应用于介质板的干涉仪性能的验证。作为验证的结果，干涉仪可以清楚地检测板的横截面形状以及其厚度。
