ABSTRACT:
Disclosed is a method for the adjusting of the detection threshold of a radar receiver for a distance zone called a search zone surrounded by distance zones called adjacent zones, fitted out with a module enabling the computation of the mean value as a function of the distance of the ambient noise along an axis starting from the receiver wherein, for each search distance zone, the detection threshold is raised by a zero value when the ambient noise is low and by a value that increases monotonically with the level of the noise measured when the ambient noise is greater than a pre-determined threshold.
