[세계로 뻗어가는 K방산] Hanwha Systems
Hanwha Systems will participate in the ‘Korea International Defense Industry Exhibition (KADEX 2024)’, which will be held for five days from the 2nd to the 6th of next month. KADEX is Korea’s largest ground weapons exhibition and will be held this year at Gyeryong University in South Chungcheong Province.
Hanwha Systems, along with Hanwha’s three defense companies, including Hanwha Aerospace and Hanwha Ocean, will promote its comprehensive capabilities in the defense industry encompassing land, sea, air, and space. At this exhibition, Hanwha Systems plans to showcase various protection systems, including the world’s best Earth observation satellite development capabilities, as well as the cutting-edge AESA radar and anti-drone system, which boasts excellent technology by recently winning several domestic and overseas projects.
Exhibition of three types of small SAR satellites developed with our technology
The SAR (Synthetic Aperture Radar) satellite, one of the Earth observation satellites, uses radar waves, so it is possible to acquire high-resolution images even at night or in cloudy weather, conditions that are difficult to observe with optical satellites.
Unlike regular satellites, the small SAR satellite developed by Hanwha Systems has an integrated payload, main body, and solar panel. It is expected that launch costs will be significantly reduced as multiple electronic components are designed to be integrated into one so that as much as possible can be loaded on the launch vehicle.
There are three types of small SAR satellites on display this time, with resolutions of △1m △0.5m △0.25m. In particular, the small SAR satellite with a resolution of 0.25m, developed independently based on Hanwha Systems’ radar technology accumulated over several decades, is the first satellite to be released in Korea through this KADEX and is evaluated as the world’s best, similar to the technology currently in operation in advanced countries.
Hanwha Systems is Korea’s only Earth observation solution company and developed Korea’s first small SAR satellite weighing less than 100 kg and having a resolution of 1 m using purely Korean technology, and successfully completed its first launch in December last year. This satellite is currently in initial operation.
From unmanned aerial vehicles to multi-purpose… Diversification of AESA radar lineup
AESA radar (Active Phased Array Radar) is mounted on the front of a fighter jet and acts as the ‘eyes’, and is one of the key pieces of equipment in a state-of-the-art fighter jet. It has the advantage of being able to detect a wider area than existing mechanical radars, and being able to perform multiple missions and engage multiple targets simultaneously.
At this KADEX, Hanwha Systems will exhibit two types of AESA radars, including △AESA radar for unmanned aerial vehicles and △AESA radar for multi-purpose surveillance, to emphasize its core sensor development capabilities for a combined aviation manned and unmanned operation strategy.
The AESA radar for unmanned aerial vehicles is smaller and lighter than the AESA radar for the Korean fighter (KF-21) and can be mounted on light combat aircraft and unmanned aerial vehicles. Both radars use air-cooling technology that can cool the radar, which generates a lot of heat, using only air. Unlike existing AESA radars, no separate cooling device is required, reducing weight and volume.
The multi-purpose surveillance AESA radar, or MMS AESA radar, was developed for surveillance and reconnaissance purposes, not for combat purposes. It has excellent detection capabilities for moving targets on land and at sea, making it optimized for surveillance, reconnaissance, and search and rescue. It is small and light, so it can be applied to various small aircraft such as manned and unmanned fixed-wing and rotary wing aircraft.
Anti-drone-air defense system that blocks drones and missiles
Hanwha Systems is developing its own anti-drone systems of various types, including facility-type, mobile-type, and net-type, that can prevent illegal drones and small unmanned aerial vehicles from infiltrating the airspace. Among these, the mobile anti-drone system, named ‘Drone response multi-layer complex protection system’, increases mobility by mounting components on vehicles for quick defense of urban areas and important areas. Omnidirectional detection is possible at 90-degree elevation angles and 360-degree azimuth angles, and it can detect and identify low-altitude small unmanned aerial vehicles and perform complex defense by distance through the use of △jammers, △capture drones, and △lasers. Through this, it is possible to respond in the event of infiltration by a drone that the surface-to-air guided weapon system was unable to defend against.
Hanwha Systems’ air defense system will also be displayed. The ‘Multifunctional Radar (MFR)’, a core sensor of the missile interception system, the medium-range surface-to-air guided weapon system (M-SAM) and the long-range surface-to-air guided weapon system (L-SAM), detects and tracks enemy aircraft and ballistic missiles in the air on the ground. You can do it. In particular, Hanwha Systems is recognized for its radar technology in the global market by supplying multi-functional radar to the medium-range surface-to-air guided weapon system (Cheongung-II), which has been exported to the United Arab Emirates (UAE) and Saudi Arabia.
Meanwhile, Hanwha Systems is participating in a total of three overseas exhibitions this month alone, including MSPO in Poland, Land Force in Australia, and ADAS in the Philippines, and is making every effort to find export routes in addition to securing domestic demand.
