AN/APR-39 Digital Radar Warning Receiver Family

The AN/APR-39E(V)2 is the next step in the evolution of the AN/APR-39, the radar warning receiver and suite controller that has been protecting aircraft for decades. This fully digital system provides 360-degree coverage to automatically detect and identify threat types, bearing, and lethality.

Based on Northrop Grumman’s ultra-wideband architecture and digital millimeter wave antennas shared with other electronic warfare programs of record, the AN/APR-39E(V)2 detects modern, agile threats and waveforms, including low power millimeter wave systems. This common building block approach enables affordable sustainment, so operators can always keep up with the state-of-the-art threat.

• Provides 360-degree threat detection, identification, and Angle of Arrival (AOA) across C-M bands for signals of any polarization • Outpaces emerging RF threats through a multi-channel digital receiver with wide instantaneous bandwidth and high sensitivity
• Handles modern and complex emitters with millimeter wave frequency, single pulse modes, and frequency- or phase-modulation • Uses an integrated processor that generates high fidelity RF signal measurements to characterize emitters and reduce ambiguities
• Reduces crew workload through easy-to-understand threat symbology and digital voice audio
• Includes a flight line reprogrammable Operational Flight Program and threat library
• Supports multiple external interfaces to meet the user’s current and future requirements

The Northrop Grumman APR-39D(V)2 Radar Warning Receiver (RWR)/Electronic Warfare Management System maximizes survivability by improving aircrew situational awareness via interactive management of all onboard sensors and countermeasures. The AN/APR-39D(V)2 provides advanced RWR capability for today’s and tomorrow’s RF threat environments. The system features the latest technology in a small, lightweight configuration that protects a wide variety of rotary, tiltrotor and fixed-wing aircraft from modern threats.

Northrop Grumman’s roots in electronic warfare are deep, with some of the world’s most trusted and advanced systems flying today.
