Abstract :
The problem of creating fast virtual oscilloscope of complex reflection coefficient based on the electromagnetic approach using cross-shaped splitter at the measurement transducer is studied. On the basis of the adequacy of the electromagnetic model and the actual design of meter the measurement error of the reflection coefficient of less than 5% and the possibility of measuring the parameters of vibrating objects in free space with an amplitude of at least 0.1 mm in the frequency range up to 1 kHz are obtained.
