I worked on the ALQ-131 in England in 1986-87, and then I became the lead field engineer for Raytheon on the ALQ-184 from 1987 to 1998. Everything I am saying here is freely available in industry publications (I checked carefully).
The ALQ-184 is a heavily modified ALQ-119. Raytheon gutted the RF bay and changed the layout. The various RF channels were standardized. The analog control section was replaced with a digital control section with 15 microprocessors.
The ALQ-131 is a modular ECM system, with removable equipment racks to provide a versatile mission package. Changing equipment configurations isn't as easy as Westinghouse made it out to be, though, so the standard package is pretty closeley adhered to. The F-16 typically flies with a shallow pod configuration. A "deep" pod configuration with an equipment gondola underneath adds another octave of frequency coverage but is dangerously deep for the F-16 centerline mount. The ALQ-131 was designed with maintenance in mind, with easy access to all the RF and control sections. Cooling is provided through an evaporative freon recirculating system.
The ALQ-184 incorporated the Rotman RF lens used in the Navy SLQ-32 shipboard ECM system. Reliability was increased using multiple mini-TWT's instead of single high gain TWT's like the ALQ-131 and -119. High gain antennas and a pulse processing receiver dramatically increased the effective radiated power of the system. Cooling is provided using coolanol 20 recirculated through a high pressure pump to radiating heat exchangers. The system is not as maintenance friendly, since the RF section is contained in a 9-inch tube and requires a great deal of effort to remove for troubleshooting.
Both systems are designed for self-protection jamming for tactical fighter aircraft. Neither system provides enough power to deny the use of the spectrum to modern weapons systems, so the objective is to achieve an acceptable miss distance by spoofing the threat radar. This is done through a variety of techniques that I won't discuss. There is no doctrine to choose one pod over another based on the mission requirement. Active units do not employ more than one type of pod. The ALQ-184 has been proven to be more effective than the ALQ-131, and doesn't have as big an impact aerodynamically, so is the pod of choice for combat units.
- Тогда AN/ALQ-131 предпочтительнее вне всяких сомнений, особенно с учётом того, что даже самолётные БРЛС имеют рабочий диапазон 8-12 ГГц, а не только радарчики УРВВ, чей рабочий диапазон уверенно дрейфует в зону миллиметровую.
Что же тут с диапазоном 2-10 ГГц делать?? "Остаётся одно только - лечь помереть"...
Что-то тут не так, что-то неладно...
Вот, и я удивился. Вообще-то, документы, которые я цитировал, датированы началом 2000-х гг, может, что-то изменилось (или в документах - ни разу не официальных - сознательная деза). Скажем, выданный Гуглем "International Electronic Countermeasures Handbook" называет для AN/ALQ-184 "low, mid, high bands". Кстати, для израильских систем, как EL/L 8262, называют частоты до 18 ГГц.
...Но, да, модулярность и потенциал "роста" AN/ALQ-131 хвалят, похоже, многие.
A series of free flight demonstrations of the Miniature Air-Launched Decoy X (MALD-X) at Naval Air Warfare Center Point Mugu, California on 20 August and 22 August were completed successfully...
The MALD-X is a next generation of decoy missiles developed by Raytheon. The air-launched missile is an expendable vehicle that is designed to look like a US or allied aircraft to enemy air defense systems.
The MALD-X is intended to be used on-board the US Navy’s Boeing F/A-18E/F Super Hornets. The current MALD decoys are compatible with and operated on-board the US Air Force’s Lockheed Martin F-16 and Boeing B-52 bomber.
The original MALD weighs less than 136kg (300lb) and has a range of approximately 500nm (926km), according to Raytheon. The company also produces a MALD-J variant, which operates as a stand-in electronics jammer.
Compared to its predecessor, the MALD-X will have an improved electronic warfare payload, the ability to carry out low-altitude flight and an enhanced net-enabled datalink. Raytheon was awarded $34.8 million by the USAF to develop a new version in 2016.
