Abstract
A method for mapping a maritime zone, in which buoys transmit and receive signals that echo off a target, and are forwarded to a processing base to determine a position and estimate a velocity of a target. The method includes producing a grid for a zone of possible presence; creating blind elliptical zones by deleting direct signals between transmitting and receiving buoys; determining an amplitude and azimuth of a cell; calculating a likelihood index of a cell; calculating a neutral index of a cell; normalizing by the neutral index and performing a base adjustment; multiplying the likelihood indexes for independent observations of buoys; and thresholding of positions to obtain a number of noncontiguous contacts, forming an Active Geographic Plot.
