(FR) RÉSEAUX D'ANTENNES
Abstract:
(EN) A RF radar that includes a first array of transmission antennas and a first array of reception antennas; wherein transmission antennas of the first array of transmission antennas are spaced apart from each other by a first distance; wherein reception antennas of the first array of reception antennas are spaced apart from each other by a second distance; wherein each one of the first distance and the second distance exceed half a wavelength; wherein the first distance differs from the second distance; wherein a ratio between the first distance to the second distance is not an integer; and wherein a ratio between the second distance to the first distance is not an integer.
(FR) La présente invention concerne un radar RF qui comprend un premier réseau d'antennes de transmission et un premier réseau d'antennes de réception ; les antennes de transmission du premier réseau d'antennes de transmission sont espacées les unes des autres selon une première distance ; les antennes de réception du premier réseau d'antennes de réception sont espacées les unes des autres selon une seconde distance ; chacune parmi la première distance et la seconde distance dépasse la moitié d'une longueur d'onde ; la première distance est différente de la seconde distance ; un rapport entre la première distance et la seconde distance n'est pas un nombre entier ; et un rapport entre la seconde distance et la première distance n'est pas un nombre entier.
