Abstract: A system determines a course of action for a vehicle. The system includes an altitude module, a threat detection module, a route module, and a threat avoidance module. The altitude module contains a list of types of threats. The list includes a predetermined threshold time for maximum safe visibility by the vehicle for each type. The threat detection module detects threats. The route module stores a planned route for the vehicle. The threat avoidance module determines types of threats detected by the threat detection module. The threat avoidance module utilizes the predetermined threshold times from the altitude module for each threat detected by the threat detection module to determine whether the planned route may safely enter visibility range of each threat detected by the threat detection module.

Abstract: A method for determining peak summit locations for multiple peaks on a three-dimensional contour includes the step of determining a highest point on the contour. Next, a peak summit of a peak on the contour is identified. The peak summit is related to the highest point on the contour. Next, the points on the contour associated with the peak on the contour are determined, and the contour is modified to zero out the points on the contour associated with the peak. The above steps are then repeated until all of the peak summits on the contour are identified.

Abstract: A method for determining a location of an emitter in a monitored area includes the step of providing an array representative of the monitored area, the array including a plurality of elements. Next, at least one first curve and at least one second curve is provided in the array. The first and second curves are representative of possible locations of the emitter in the monitored area. Then, possible emitter locations are identified at intersections of the first and second curves. The intersections are identified by determining locations in the array where an element having an assigned attribute corresponding to a first curve has a predetermined number of adjacent elements having an assigned attribute corresponding to a second curve.
