The CID ACTD provides the user an operational capability, the means to evaluate the potential new capability in terms of its military utility, and a sound basis for adapting the warfighting concept of operation to maximize effectiveness of the new capability. This ACTD includes hardware funded under non-S&T PEs, including the Army Battlefield Combat ID System, Navy Situation Awareness Beacon with Reply (SABER) project, and Air Force Situation Awareness Data Link (SADL) project. One objective is to demonstrate an interoperable air-to-ground and ground-to-ground combat identification capability with a minimum probability of correct identification of 0.90. Additionally, identification will be demonstrated effectively at 1.5 times the effective range of the weapon. The ACTD will comprise numerous cooperative CID systems (both question-and-answer and digital radios) and one noncooperative technique (RF emitter geolocation and real-time specific emitter identification (SEI)).

Multisensor/multifeature fusion algorithm developments are being examined by the Air Force Air Target Algorithm Development (ATAD) program for air targets, and will be tested in the ATAD flight demonstration in FY98. The Navy Noncooperative Air Target Identification program provides advanced inverse synthetic aperture radar imaging techniques for air targets via an adaptive-range Doppler imaging process (roofhouse demonstration in FY99). Exit criteria for air target identification (20 classes) under this DTO are (1) declaration probability of 85% and (2) identification confidence probability of 99%. For surface targets, the DARPA/Air Force Moving and Stationary Target Acquisition and Recognition (MSTAR) program is developing model-driven automatic target recognition (ATR) synthetic aperture radar technologies. The Navy Littoral Surveillance/Moving Target Recognition program will provide a demonstration of imaging small craft (flight demonstration in FY98). The Air Force Air-to-Ground Radar Imaging program will demonstrate an advanced one-dimensional radar imaging/identification technique in a fire control radar (flight demonstration in FY01). Exit criteria for surface target identification under this DTO are (1) declaration probability of 85% and (2) identification confidence probability of 98%.

These radar technologies will be jointly flight tested by the Air Force and Navy. Plans are also being made for participation in the annual All-Service Combat ID Evaluation and Test exercises conducted by the Joint Combat ID Office and sponsored by GOSC-ID.
