AN/APR-39 Digital Radar Warning Receiver Family

A Smarter, More Agile Radar Warning Receiver

The electronic battlefield becomes more complex every day, dominated by an array of multispectral — radio frequency/infrared/electro-optical (RF/IR/EO) — threats that jeopardize aircrew survival. To survive, aircrews must have not only sophisticated digital radar sensors and countermeasures but also a way to manage them.

APR-39E(V)2

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.

AN/APR-39E(V)2 Benefits

  • 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
