AN / ALR-67

from Wikipedia, the free encyclopedia

The AN / ALR-67 is a digital radar warning system for combat aircraft . It is used by the US -Konzernen Raytheon and Northrop Grumman produces.

description

The ALR-67 was designed to warn pilots of combat aircraft in good time before a detection by radar systems . For this purpose, several antennas are distributed over the airframe of the carrier aircraft in order to ensure seamless monitoring of the airspace. Typically these are located on the wing edges and in the area of ​​the cockpit . The system can detect and identify radar radiation in the frequency range from 0.5 to 20 GHz. Reprogramming is also possible so that new radar systems can also be identified.

Components

variants

Note: The original configuration of the ALR-67 was almost completely replaced by the (V) 2 and (V) 3 variants.

AN / ALR-67 (V) 2

This variant has been the US Navy's primary radar warning system since the 1990s and is manufactured by Northrop Grumman. It can be connected to various other systems, for example with the AGM-88 HARM to the radar control, the decoy AN / ALE-47 or EloGM systems of the type AN / ALQ-126 , - 162 or - 165 . In addition, a connection with the on-board radar and communication systems ensures their trouble-free operation. With this variant, new algorithms were introduced compared to the previous version , which, among other things , can provide precise coordinates even under high g load.

By July 2001 over 2,100 devices had been produced and delivered. These have been exported to a large number of countries.

AN / ALR-67 (V) 3

The ALR-67 (V) 3 (also called "Advanced Special Receiver" called) is produced by Raytheon and represents a significant advancement of the (V) is 2 variant So the old main processors by were. COTS - derivatives of the G4 CPU replaced. The original helical antennas have been replaced by so-called "Integrated Antenna Detector" devices (AID), which can monitor a broader frequency range (especially in the range of very high frequencies) and any polarization .

The system has been in series production since mid-1999 and is currently only used to equip the F / A-18E / F Super Hornet , with the system also being exported to Australia .
