A system and method is provided for detecting emitter signals and for determining a scan strategy for a receiver system that receives such emitter signals. Data is provided that specifies one or more emitters or emitter types desired for detection. An algorithm evaluates the cost, in terms of receiver resources, of using one or more different detecting methods to create a receiver scan strategy for the desired emitters or emitter types.
