The U.S. Department of Defense faces an increasingly complex electromagnetic environment, in which rapid advances in radar and electronic warfare (EW) demand new tools for development, testing, and training. DARPA’s Digital RF Battlespace Emulator (DRBE) program took up this challenge, resulting in the world’s largest high-fidelity, real-time virtual radio frequency (RF) test range – enabling previously unachievable scale and realism in the emulation of EW scenarios.

Unlike traditional modeling, simulation, and open-air testing approaches, the DRBE system
