aCHR Overview
The aCHR is a cutting-edge, ground-based, multi-mission radar for Active Protection Systems (APS), Vehicle Protection Systems (VPS), Hostile Fire Detection (HFD), Counter-UAS, and Hemispheric Surveillance operational missions.
This pulse-Doppler, software-defined, S-band radar platform incorporates an AESA antenna and GaN amplifiers with advanced 4D processing capabilities, providing unprecedented clutter handling and multipath mitigation.
The aCHR is a best-of-breed radar with exceptional situational awareness and survivability during combat that offers superior SWaP-C and On-The-Move operation capabilities.
