This proposal describes the significance of the combat identification problem, how EW plays a role, the state of current EW ID, followed by five technical objectives for this effort which would lead to improved EW ID: (1) technique development, (2) technical analysis of the technique, (3) technique performance analysis, (4) technique shipboard integration plans, and (5) identification of techniques for further improvement. The technique proposed for development and technical performance analysis is an innovative application of inferential technology to real-time tactical EW and intelligence databases. The innovations of the techniques are described. Integration with existing shipboard EW experiments is described. Some preliminary identification of techniques based upon more thorough signal exploitation is provided.
