Millimetric wave device, capable of operating as a signal transceiving antenna, with an optimum image definition even at extremely short distances (about 1 mm). Depending on the more or less concentration of the waves, the so realised radar antenna adopts, in its different configurations, a curved front optics, or an optics of hemispherical, aspherical, parabolic, concave, convex, biconcave, biconvex or stepped optics. The real focal length of the radar is shorter than the one of the lens utilised in said antenna. The standard dimensions of the electronic transception and processing circuit part are very limited and contained. <IMAGE> |
