Systems and methods are provided for locating threats to an aircraft that are located on the ground. Associated bearings are determined from an aircraft for each of a plurality of detected shots from a threat at ground level. A plurality of pairs of bearings are selected, and a weight value is calculated for each selected pair of bearings. An estimated position for the threat is determined from each selected pair of bearings. An improved estimation of the position for the threat is calculated as a weighted combination of the estimated positions.
