Abstract:
1. A method of managing a flight path of an aircraft subject to a threat, the method comprising the steps of: a. receiving threat data; b. receiving flight path data including a location of each of a plurality of preselected mission waypoints; c. computing a simulated waypoint along the flight path, the simulated waypoint located between two of the plurality of preselected mission waypoints; d. computing line of sight LOS vectors from the location of the simulated waypoint to locations of threats, each of the LOS vector having an azimuth parameter, an elevation parameter, and a range parameter; e. determining a probability of threat detection by the threat using the computed LOS Vector; f. creating a volumetric perturbation by, perturbing the parameters of Azimuth, elevation, and range to generate a plurality of perturbed LOS vectors each having one or more or all of its respective parameters of azimuth, elevation, and range having perturbed values; g. altering the flight path based on the volumetric perturbation; h. assigning a threat value from among each probability of threat detection by the threat determined using the computed LOS vector and each of the plurality of perturbed LOS vectors; i. determining if the maximum probability of threat detection value of the threat exceeds an acceptable probability of detection value of the threat; and j. if the maximum probability of threat detection value of the threat exceeds the acceptable probability of threat detection value, performing the step of generating, a list of a plurality of candidate waypoints.
