Research Abstract

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.
