Abstract (en)
1. A radar transmission-receiving arrangement, comprising a so-called "Doppler" module, having an aperture through which the actual transmission and reception are effected, a partially reflecting dielectric sheet and a dieletric lens which is positioned at a predetermined distance from the dielectric sheet by mechanical means being placed in front of the aperture of the module, characterized in that the partially reflecting sheet and said mechanical means are constituted by a foam block, which has a first plane face arranged in front of the aperture of the "Doppler" module and a second plane face paralel to the fist face, against which the dielectric lens is placed.
Abstract (fr)
Dans un mini radar de détection de présence une plaque partiellement réfléchissante est placée devant l'orifice d'un dispositif émetteur-récepteur (1) et, en avant de cette plaque est disposée une ientiile (7) qui est destinée à accroître la directivité du système. Un bloc de mousse (9) rigide assure à lui seul la fonction de plaque semi-réfléchissante (5) et la tenue mécanique de la lentille.
