Abstract

Embodiments of a method and apparatus for assigning electromagnetic-spectrum (ES) jamming assets are generally described herein. In some embodiments, the method includes dividing an electronic warfare (EW) support area into a grid. The method may further include determining a vulnerability area (VA) of the entity based on planned route information of the entity within the EW support area. The VA may include portions of the grid. The method may further include assigning a first jamming asset to the VA based on a coverage capability of the first jamming asset. The coverage capability may include a number of contiguous portions of the grid.
