Abstract (en)

[origin: WO2006032569A1] The invention relates to an antenna radar system comprising a short-range antenna path (310 - 365), and a long-range antenna path (210 305) separate from the short-range antenna path (310 - 365). According to the invention, a push-pull mixer (345 - 360) is especially arranged in the short-range antenna path. A heterodyne frequency translation or mix of the signals to be processed can be carried out by means of the push-pull mixer (345 - 360) in the short-range antenna path.
