Radar detector for vehicle suitable in close range applications

Vehicle radar detector for short-range applications with an antenna (1) subjected to a mechanical scan and a transceiver (2) of pulse signal at a millimeter wavelength, wherein said antenna (1) is molded type plane network; said transceiver (2) forms a rigid and inseparable assembly with the antenna (1) and is constituted by a controlled dual-frequency oscillator and by means for heterodyne conversion of the reception signal; the antenna-transceiver assembly (1, 2) is supported by a molded element (3) which is mechanically scanned within a radome housing (6) for attachment to the vehicle; and comprising an optoelectronic type angular restitution module (5) for detecting the In particular, said transceiver (2) transmits the pulse signal with a low repetition cycle and is kept active during the period of reception of the radar echoes to the maximum distance concerned.
