ABSTRACT:
An obstacle sensor operating by collimation and focusing of the emitted wave comprises: a device (I) for insulating the electromagnetic waves emitted by a generator (1); a device for the automatic control (12, 12′) of the transmitter and of the sensor status; a device (15′÷15″′) for amplifying the power of the signals emitted and/or received; different shapes of output lens (14′÷14″′) of the antenna, with or without peripheral lobes (16), associated or non associated to microwave sensors (19). The sensor is associable to passive and/or active obstacle warning reflectors with the possibility of discriminating them not only if front but also side and above and below the horizon central azimuth, for road, aircraft and naval applications.
