Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Überwachung eines Gebietes mit Hilfe einer Radaranlage. Dabei wird eine Sende-/Empfangsantenne, vorzugsweise ein phasengesteuertes Antennenarray ('phased array') mit mehreren benachbarten Sende-Keulen verwendet. Die von diesen ausgesandten unterschiedlich codierten Sendesignale werden zeitlich nacheinander über ein Ziel geschwenkt und das Echosignal mit Hilfe eines Matched Filters ausgewertet. Mit dem Verfahren ist eine erhebliche Verringerung der von den einzelnen Sende-Keulen ausgesandten Sendeleistung möglich.
(EN)
The invention pertains to a method for territorial surveillance with the aid of a radar system, using a duplexer, preferably a phased array with a number of adjacent radiation lobes. The differently coded signals transmitted by said radiation lobes are scanned in succession over a target and the echo signal is evaluated using a matched filter. The method makes it possible to reduce substantially the transmitting power of the individual radiation lobes.
(FR)
L'invention concerne un procédé de surveillance d'une zone à l'aide d'un système radar, selon lequel on utilise une antenne émettrice/réceptrice, de préférence une antenne-réseau à phase commandée pourvue de plusieurs lobes de rayonnement adjacents. Les signaux diversement codés que ces lobes de rayonnement émettent, sont orientés successivement sur une cible et le signal d'écho est évalué à l'aide d'un filtre adapté. Ce procédé permet de réduire considérablement la puissance d'émission des lobes de rayonnement individuels.
