ABSTRACT:
A method of processing an electromagnetic signal received and contained completely within the bounds of a two dimensional signal detection array, is comprised of (a) determining a position of the signal in a large window on the detector array, (b) reducing the dimensions of the window by a predetermined ratio with the position of the signal at the center thereof, (c) locating the position of the signal in the reduced size window (d) repeating steps (b) and (c) until the window is a predetermined number of pixels in size, and (e) continuously monitoring the presence and location of the signal.
