A light beam scattered from the target in response to illumination by the designator is received and projected on a detector as an unfocused spot. The detector is divided into a plurality of sectors, each sector being adjacent to two sectors and all sectors meeting at a common point. Each sector outputs a signal indicative of a respective energy of the portion of the light beam illuminating the sector of the detector. A sum of the signals is determined.
