HIGH-PRECISION ABSOLUTE MICROWAVE TELEMETER WITH A MULTI-STATE REFLECTION DEVICE

摘要

The present invention relates to a system for measuring the distance between an antenna (111) and a reflector (112), including a transmission/reception module (140), a measurement means (160) for measuring a parameter equal to the complex ratio between the wave received and transmitted by said transmission/reception module for a plurality of frequencies, as well as a calculation means (170) for calculating an inverse Fourier transform of said parameter and measuring the time position of a spike in the corresponding impulse response. A first time position of a spike is measured in a differential impulse response between first and second radio statuses of the reflector. A second time position corresponding to the reflection on the antenna is also measured, and the distance is obtained from the first and second time positions.
