<p>A system for warning of the proximity of an obstacle within a zone of interest adjacent to a vehicle includes at least one primary sensor configured to produce a primary output indicative of a quantity of electromagnetic radiation incident on the primary sensor from the zone of interest. Also provided is a device for generating a compensation output indicating a quantity of background electromagnetic radiation incident on the primary sensor. A number of transmitters transmit an electromagnetic signal towards the zone of interest. A compensation module responds to the compensation output to vary a transmission power of the electromagnetic signal. A processing module associated with at least the primary sensor generates a warning signal in response to the primary output. <IMAGE></p> |
