Radar detector for vehicle suitable in close range applications.

摘要

Radar detector for vehicle suitable for close range applications with an antenna (1) subjected to a mechanical scanning and a millimetre-wavelength pulsed signal transceiver (2), in which the said antenna (1) has a flat array of moulded type; the said transceiver (2) forms a rigid and inseparable assembly with the antenna (1) and it consists of a driven dual-frequency oscillator and of means of performing a heterodyne conversion of the signal at reception; the antenna-transceiver assembly (1, 2) is supported by a moulded element (3) which is subjected to a mechanical scanning inside a housing with radome (6), intended to be fixed to the vehicle; and comprising an angle-restoring module (5) of optoelectronic type for detecting the angle of aim of the antenna and its direction of rotation. In particular, the said transceiver (2) transmits the pulsed signal with low repetition cycle and it is kept activated during the period of reception of the radar echoes up to the relevant maximum range. <IMAGE>
