At EW Europe 2019 in Stockholm this week, Hensoldt is introducing its new KALAETRON radar warning receiver (RWR), "which revolutionises the protection of aircraft and helicopters from radar-guided weapons," the company states.

“With the help of the latest artificial intelligence and digital signal processing methods, our KALAETRON RWR detects radar-based threats early and reliably,” explains Celia Pelaz, Head of Hensoldt's Spectrum Dominance / Airborne Solutions Division. “Our new product thus increases the assertiveness of aircraft and helicopters and their survivability, especially in view of the increasingly dense signal spectrum and the growing threat posed by highly integrated air defence systems.”

Due to its fully digital design, the new radar warner detects and identifies threats incredibly quickly and with an very low false alarm rate, over an extremely wide frequency range. KALAETRON uses artificial intelligence (AI) techniques to detect new threat patterns from a huge amount of collected raw data. This is especially important to identify the latest air defence radar systems that cover an extremely wide bandwidth or which hop between particular frequencies in fractions of a second. KALAETRON thus enables fighter or transport aircraft to be protected even against upcoming anti-aircraft weapons and integrated air defence systems, while also offering great potential for adaptability to cope with future threats.
