Electronic Support Measures (ESM) Target Generator System (TGS) at the U.S. Navy's Atlantic Undersea Test and Evaluation Center (AUTEC) on Andros Island in the Bahamas. The system generates simulated radar threat emissions and can emulate any known friendly or enemy radar system. Developed as part of AUTEC's Improvement and Modernization Program, the ESM TGS can emulate up to 64 threat radar modes dynamically. The system is also completely reprogrammable, a key distinguishing feature. "The ESM TGS system represents a major enhancement to the Navy range's ESM test and evaluation capability, particularly for advanced receivers located on ships, helicopters, aircraft and submarines," said Dr. Edward Eberl, president of Amherst Systems.
