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. A plurality of ratios is determined, each ratio corresponding to a respective sector and being calculated by dividing a signal from the respective sector by the sum of the signals. The orientation of the system with respect to the target is determined based on the three ratios, via a look-up table and/or via one or more algorithms."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Laser spot tracking receiver","description":"A technique is presented for tracking a target illuminated by a laser designator.
