AN / ALR-93

The AN / ALR-93 is a digital radar warning system for combat aircraft . It is from the US Corporation Northrop Grumman produces.

description

The ALR-93 was designed to warn pilots of combat aircraft in good time before a detection by ground-based radar systems . For this purpose, four antennas and a superimposition receiver are attached to the airframe of the carrier platform. 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.

According to the manufacturer, the system should have a detection probability of almost 100%, with the database comprising around 2000 signal profiles. The software is written in C and is executed by PowerPC CPUs. The system is connected to the avionics of the carrier platform via the MIL-STD-1553 data link in order to avoid interference with on-board radar and communication systems. In 2003 it became known that the ALR-93 was being used as a radar warning component in the ASPIS EloKa complex.
