  • providing an array representative of the monitored area, said array including a plurality of elements;

    providing at least one first curve and at least one second curve in said array, said at least one first and second curves being representative of possible locations of the emitter in the monitored area; and

    identifying possible emitter locations at intersections of said at least one first and second curves, said intersections being identified by determining locations in said array where an element having an assigned attribute corresponding to said at least one first curve has a predetermined number of adjacent elements having an assigned attribute corresponding to said at least one second curve.
