AN / ALQ-126

from Wikipedia, the free encyclopedia

The AN / ALQ-126 is an airborne system for electronic countermeasures at short to medium distances. It was created by the US Corporation Associates Sanders produced, which is now part of BAE Systems is.

development

The development of the ALQ-126 began in 1969 with the aim of replacing the now outdated AN / ALQ-100 . Production began in 1973 and a total of 1,828 devices had been delivered by the end of production in 2000. As the system is still actively used in many countries, BAE continues to offer support . Two further variants were developed during the production phase: the ALQ-126B, which represents a general increase in performance, and the ALQ-164, an external container-supported derivative of the ALQ-126B with an additionally integrated AN / ALQ-162 - CW interference system.

technology

The ALQ-126 is designed to missiles with monopulse - or Minimumpeilungs - radar seeker to bother. Since the system is mainly used for self-protection, it is light and consumes little energy, but it cannot interfere with strong radars (e.g. from SAM positions or AWACS machines). In order to be able to react to new threats, it is possible to reconfigure parts of the software in a short time. The ALQ-126 absolutely requires a connection to the radar warning system of the carrier aircraft in order to be able to adapt its interference technology. To further increase efficiency, it is often connected to an AN / ALQ-162 , which can also be used against CW radar devices. Since the system has long been used on a wide range of aircraft, it has been used in many conflicts. The performance is rated as satisfactory, with reprogramming of the software often causing problems so that maximum efficiency could not be achieved in many cases.
