ABSTRACT:
A method of detecting a heat source in an area to be watched consists of disposing a detector on a support elevated with respect to the area to effect a sweeping motion at least in a horizontal plane. Points in the area to be watched are defined by the angular position of the detector in the horizontal and vertical planes when the detector is directed toward a point and by at least one associated additional data element that impounds the geographic position of the point in a predetermined reference system.
