Description

The pod provides self protection jamming for tactical fighter aircraft and is designed to operate in a dense, hostile environment of radar directed (RF) threats that require high duty cycle (pulse doppler) or CW jamming techniques. The ALQ-131 is modularly constructed, containing numerous receivers, antennas, and transmitters, active over up to five frequency bands, designed to jam, deceive, and confuse threat radar homing missiles. Because the ALQ-131 pod is modular, the system can be configured to cope with a range of threats by selecting individual modules for inclusion in the pod. The AN/ALQ-131 pod is capable of producing both "white noise" and deception jamming signals. The pod is controlled from the cockpit by both automatic and manual systems. Basic hardware components include an Interface and control module, 2 or 3 Band modules that cover a portion of the pod's total frequency range, and the Receiver/Processor (R/P) module. The R/P module combines an accurate signal identification capability with power management. An important function of the R/P is the management of "look through" which permits periodic surveillance of the threat environment while jamming is in progress. The AN/ALQ-131 pod is certified for use with All American tactical aircraft as well as many Western or NATO tactical aircraft.
