DARPA’s announcement of DRBE signals a shift in how defense systems will be designed and validated in the digital era. At its core, DARPA says DRBE is an ultra-high-density simulation platform capable of reproducing real-world EMS conditions with hundreds of simultaneously active, full-duplex channels. “DRBE is a leap forward in how we can prepare and equip RF systems against sophisticated adversaries,” DRBE program manager in DARPA’s Microsystems Technology Office, Dr. Anna Tauke-Pedretti, said in a statement. With DRBE, DARPA is looking to overcome these constraints by creating a digital twin of the electromagnetic battlespace. It has the potential to be a strategic enabler for next-generation defense technologies,” Dr. Tauke-Pedretti explained.
