OVERVIEW:
The AN/ALQ-99 Tactical Jamming System is the first fully integrated computer controlled support jamming system. The AN/ALQ-99 intercepts and automatically processes radar signals and power manages the system's transmitters to effectively jam large numbers of diverse radar threats with very high effective radiated power (ERP). Since the deployment in the early 1970's aboard US Marine Corps and US Navy carrier-based EA-6B Prowler aircraft, the system has undergone multiple upgrades. The EA-6B/ALQ-99 combination has become an indispensable fleet asset, fully integrated into all air wing combat missions.
The AN/ALQ-99 Tactical Jamming System (TJS) on board system includes the receiver, processor, and aircrew interfaces. The TJS also includes a selection of mission-configured jammer pods carried as external stores. Each jammer pod contains a ram air turbine generator, two selectable transmitter modules with associated antennas, and a universal exciter which is interfaced with and controlled by the on board system and aircrew. The modular open architecture of the jammer system, which facilitates optimizing transmitters and antennas for a given frequency range, also facilitates tailored mission configurations.
The AN/ALQ-99(V) Receiver Processor Group (RPG) system was developed for use in the severe interference environment of the EA-6B jamming aircraft. The RPG had completed Operational Assessment and obtained a recommendation for production before program cancellation in 1993. Six RPG EDM systems were delivered. The AN/ALQ-99 RPG provided precision direction finding, passive ranging, identification, and threat warning, and was intended for the Navy EA-6B ADVCAP aircraft in very dense environments and in the presence of onboard jamming. This system included look-through, look-above, and look-around techniques to control the interference, as well as processing algorithms to contend with the resulting fragmented pulse data. The RPG performed surveillance, radar warning, and countermeasures management in support of standoff and escort jamming missions. The system uses four quadrants of AZ/EL interferometer arrays for full azimuth coverage precision mono pulse DF measurement. The receiver is a narrow band channel cued receiver architecture with a wide instantaneous bandwidth and multiple cued narrow band channels for simultaneous pulse measurement capability. The RPG performed real time look through control of the ALQ-99 jammers to accomplish all required threat emitter detection and measurement functions without degrading jammer effectiveness. To achieve this, data processing algorithms were developed with look through samples providing as little as 1% of an emitter's pulses.
The US Air Force provided the AN/ALQ-99 to its EF-111 Raven electronic warfare aircraft along with the AN/ALQ-137 for self-defense purposes. The US Navy provided the ALQ-99 to its EA-6B Prowler fleet. Each EA-6B can carry up to five EW pods. The US Navy also plans to provide the AN/ALQ-99 to its future EA-18G electronic attack aircraft beginning in 2009.
