Six-port Based Wave Correlator with Application to Micro-displacement Measurement

摘要：

　　As a remote sensing application of the six-port based wave-correlator(SPC),measuring the micro displacement of an object is discussed in this paper.This application indicates that it is applicable for various situations to measure the micro displacement.The SPC is a two-channel wave receiver for determining the vector relation,both amplitude and phase difference,between the two input signals by measuring the power levels.A measurement system with an MMIC SPC is developed,which includes differential amplifiers,AD converters,control circuits,and microwave components.In the preliminary experiments,the results of the micro displacement obtained are with a relative error within approximately 30%compared with the ideal values,which exemplifies the possibility of the developed measurement system in the practical application.
