Abstract
(DE)
Die Erfindung betrifft ein Radar-Verfahren zum Signalaustausch zwischen mindestens zwei nicht-kohärenten Sende-Empfangseinheiten, die jeweils zunächst nicht- synchrone, insbesondere ansteuerbare, Taktquellen aufweisen, das folgende Schritte aufweist: eine Synchronisation, bei der Taktoffsets und/oder Taktraten der Taktquellen der mindestens zwei Sende-Empfangseinheiten angeglichen werden; ein Vollduplex-Messverfahren, bei dem ein erstes Sendesignal der ersten Sende- Empfangseinheit an die zweite Sende-Empfangseinheit und ein zweites Sendesignal der zweiten Sende-Empfangseinheit an die erste Sende-Empfangseinheit über einen Funkkanal, übertragen werden, wobei die Synchronisation vor dem Vollduplex- Messverfahren derart durchgeführt wird, dass ein Zeitversatz und/oder ein Frequenzversatz zwischen den Sendesignalen während einer Übertragungszeit des Vollduplex-Messverfahrens zumindest im Wesentlichen konstant bleibt/en.
(EN)
The invention relates to a radar method for signal exchange between at least two non-coherent transceiver units which each have initially non-synchronous, in particular controllable, clock sources, which method comprises the following steps: synchronization in which clock offsets and/or clock rates of the clock sources of the at least two transceiver units are adapted; a full-duplex measuring process in which a first transmission signal of the first transceiver unit is transmitted to the second transceiver unit and a second transmission signal of the second transceiver unit is transmitted to the first transceiver unit via a radio channel. Synchronization prior to the full-duplex measuring process is carried out in such a way that a time offset and/or a frequency offset between the transmission signals at least substantially remain(s) constant during a transmission time of the full-duplex measuring process.

L'invention concerne un procédé de radar servant à l'échange de signaux entre au moins deux unités d'émission-réception non cohérentes, qui comportent respectivement d'abord des sources d'horloge non synchrones, en particulier pouvant être pilotées. Le procédé selon l'invention comporte des étapes suivantes : une synchronisation, lors de laquelle des décalages d'horloge et/ou des cadences d'horloge des sources d'horloge des deux unités d'émission-réception ou plus sont ajustés ; un procédé de mesure en duplex intégral, dans lequel un premier signal d'émission de la première unité d'émission-réception est transmis à la deuxième unité d'émission-réception et un deuxième signal d'émission de la deuxième unité d'émission-réception est transmis à la première unité d'émission-réception par l'intermédiaire d'un canal radio. La synchronisation est effectuée avant le procédé de mesure en duplex intégral de telle manière qu'un décalage temporel et/ou un décalage de fréquence entre les signaux d'émission restent au moins sensiblement constants pendant une durée de transmission du procédé de mesure en duplex intégral.
