Northrop Grumman’s AN/ALQ-257 Integrated Viper Electronic Warfare Suite (IVEWS) has completed U.S. Air Force Laboratory Intelligence Validated Emulator (LIVE) testing.
The system demonstrated the ability to counter modern radio frequency (RF) threats. This was the first time the ultra-wideband architecture in IVEWS underwent LIVE testing, the company said in an official release.
During the test, simulated air defense radar pulses were injected directly into IVEWS to verify the suite’s ability to recognize and counter advanced threats. The signals used in LIVE testing are validated models that provide realistic representations of radio frequency threats. LIVE is an intelligence validated, closed-loop RF direct-injection threat radar emulator based on threat capabilities and features. It allows for the testing electronic warfare systems in realistic environments.
Fully digital and founded on secure, modular, open systems design principles, the receiver/exciter architecture in IVEWS provides advantages over heritage systems. This technology allows for extended frequency coverage, full spatial coverage, and rapid responses. Featuring efficient broadband power amplifiers and adaptive countermeasure modulations, it is designed to detect, identify, locate, and defeat next generation sensors and weapons.
IVEWS is a program of record electronic warfare suite for the U.S. Air Force F-16 fleet. The system is exportable for current and previous generations of F-16 aircraft.
