Abstract
(DE)
Bei diesem Radarsensor ist zwischen einem Mikrowellengenerator und einer Antenne ein Phasenschieber eingesetzt, der zwischen zwei Phasen umschaltbar ist. Ein Demodulator (DM) demoduliert das empfangene reflektierte Signal, welches vom Mikrowellengenerator stammenden Mikrowellensignal überlagert ist. Eindem Demodulator (DM) nachgeschalteter Demultiplexer (DEMUX) trennt die beiden phasenverschobenen demodulierten Signale. Das Meßergebnis ist weitgehend rauschfrei.
(EN)
In the proposed radar sensor, a phase shifter which can be switched between two phases is interposed between a microwave generator and an antenna. A demodulator (DM) demodulates the received reflected signal on which the microwave signal from the microwave generator is superimposed. A demultiplexer (DEMUX) downstream of the demodulator (DM) separates the two phase-shifted demodulated signals. The measurement result obtained is largely free of noise.
(FR)
L'invention concerne un capteur radar dans lequel un déphaseur, commutable entre deux phases, est monté entre un générateur hyperfréquence et une antenne. Un démodulateur (DM) démodule le signal réfléchi reçu auquel est superposé le signal hyperfréquence provenant du générateur hyperfréquence. Un démultiplexeur (DMUX) monté en aval du démodulateur (DM) sépare les deux signaux démodulés déphasés. Le résultat de mesure est largement exempt de bruit.
