In the air combat system, fire control radar undertakes core tasks such as target detection, tracking, and weapon guidance. Traditional fire control radar is limited by size, weight, and cooling requirements, and is mainly equipped on large fighter jets. To meet the demand for advanced fire control radar on lightweight platforms such as small drones, light attack aircraft, and helicopters, Raytheon has launched a small active electronically scanned array radar called "Phantom Attack". According to reports, the advantage of this fire control radar lies in its miniaturization and lightweight design. Its weight is controlled within 68 kilograms, with a compact structure and low power consumption. At the same time, this type of radar adopts a fully air-cooled design, without the need for a liquid cooling system, which can adapt to various platforms that were previously unable to equip high-performance fire control radars due to space, weight, and cooling limitations, including drones, light attack aircraft, and helicopters. At present, the Korean Aviation Industry Group has confirmed the purchase of the radar for the FA-50 light attack aircraft manufactured by the group. The "Phantom Attack" radar has multiple technical features of modern radar. Firstly, utilizing gallium nitride technology. This type of radar transmission unit uses gallium nitride components, which have high power density and efficiency, allowing the radar to maintain a certain output power and detection distance while reducing its size, enabling long-distance detection. Secondly, use digital beamforming and processing technology. This type of radar uses digital beams, which have high flexibility in scanning, focusing, and turning. It can simultaneously scan, track, identify, and lock multiple targets, and also supports switching between multiple working modes such as air-to-air and air to ground, adapting to different combat tasks. Thirdly, it is easy to use and maintain. This type of radar has a shorter start-up time and a longer design failure interval (10000 hours), which means it has a lower expected failure rate and a longer stable operation time, which can reduce certain maintenance costs. Raytheon Company stated that the emergence of the "Phantom Attack" radar provides a relatively controllable radar upgrade solution for existing old fighter jets and helicopters, which can enhance the detection, tracking, and fire control capabilities of fighter jets without the need for large-scale aircraft modification. The price is only half of the current mainstream fire control radar. This type of radar can also be used to enhance the combat capability of lightweight platforms, enabling unmanned aerial vehicles, light attack aircraft, helicopters and other lightweight platforms with limited payload to be equipped with fire control radar, improving their beyond line of sight detection and precision strike capabilities. At present, the "Phantom Attack" radar has completed flight testing, demonstrating its integration and operational capabilities on lightweight platforms. In the future, the actual deployment effect remains to be observed. (New Society)
