TELEMETRE HYPERFREQUENCE A COMMUTATION DE RETARDS

The reflector (112) has an antenna (111) and a delaying unit for delaying a reflected signal with respect to a signal received by the antenna. The reflector has distinct reflection coefficients in two radioelectric states. The delaying unit has delaying lines and switching units that select one of t...

Zusammenfassung:	The reflector (112) has an antenna (111) and a delaying unit for delaying a reflected signal with respect to a signal received by the antenna. The reflector has distinct reflection coefficients in two radioelectric states. The delaying unit has delaying lines and switching units that select one of the delaying lines from the delaying lines. A duplexer (130) is connected to the antenna, and an output of a variable gain amplifier is connected to an input of the duplexer. Independent claims are also included for the following: (1) a method for measuring relative displacement of an electromagnetic reflector (2) a method for measuring distance of an electromagnetic reflector with respect to a reference position.
