System for measuring distance between measuring antenna and electromagnetic reflector, has calculating unit calculates distance from temporal positions corresponding to reflection of emitted wave on measuring antenna

摘要

The system (100) has a measuring unit (160) for measuring parameter equal to complex ratio between signals. A calculating unit (170) performs the inverse Fourier transform for the averaged parameter so as to obtain an average impulse response to determine a temporal position of a signal peak in the response. The calculating unit calculates distance from temporal positions corresponding to the reflection of an emitted wave on a measuring antenna (111). Independent claims are also included for the following: (1) an electromagnetic reflector (2) a method for measuring a distance between an antenna and an electromagnetic reflector.
