Abstract

Systems, devices, and methods efficiently calculate optimal flight paths for protected entities given terrain data, aircraft position, flight characteristics, and positions of known threat emitters. The systems and methods execute within the mission planning timeline, and the developed processes allow users to retrieve data from the calculations to effectively place an electronic attack platform at the right place and at the right time to be effective. The calculated optimal flight paths are displayed or otherwise visualized in the mission space. Electronic attack jamming capabilities are combined with projected threat emitter performance information in order to obtain optimal geometrical positioning of the electronic attack relative to the threat emitter. Threat emitter system characteristics are combined with electronic attack aircraft capabilities while simultaneously incorporating the position of the protected entity aircraft and rendered to assist the electronic attack aircrew in providing optimal electronic attack capabilities to protect one or more entities.
