Korea Achieves Breakthrough in Radar Stealth Technology with AI-Powered Components

Breakthrough in Domestic Radar Stealth Technology

The Korea Research Institute of Standards and Science (KRISS) has achieved a significant milestone in the field of radar stealth technology. Through indigenous development, KRISS has successfully localized core radar stealth technologies, marking a crucial step towards establishing stealth weapon systems in Korea 1

The Importance of Stealth Technology

As global military tensions rise and competition in advanced weapon development intensifies, the development of stealth weapon systems has become increasingly important. Radar stealth technology, which absorbs or scatters electromagnetic waves to avoid detection by enemy radar, is a key element in ensuring both autonomy and concealment in weapon systems 1

Key Technological Advancements

KRISS has made two major technological breakthroughs:

1. Frequency Selective Surface (FSS) Design Software: This AI-enhanced software is optimized for analyzing radome structures composed of multilayer composite materials. It delivers over a 50-fold increase in design speed compared to conventional tools 1

Radomes: A Critical Component

Radomes are hemispherical structures that enclose radar and communication antennas on various vehicles. They must be precisely designed to protect internal systems while allowing electromagnetic signals to pass through with minimal distortion. In defense applications, radomes face extreme conditions and must meet multiple performance requirements 1
