| Abstract: | The problem of finding an optimal aircraft trajectory subject to constraints defining distance of detection to hostile radar stations is considered. The purpose is to find a trajectory minimizing the flight time between two given positions without hostile radar detection. The flight path is represented using a smooth curve in the form of a spline approximation. The spline representation is used to derive the heading- and bank angles of the aircraft. The position of the aircraft together with the bank- and heading angles are used for calculations of the radar detection range. Furthermore, an example in three dimensions when a Saab 105 approaches a radar station in level flight is investigated. |
