WALLSENSE is an ultra-lightweight Through-Wall Radar (TWR) technology developed by DefTech, designed to detect, locate, and track human targets, motion, and vital signs (such as breathing micro-movements) behind solid structural barriers. Traditional tactical through-wall radar systems typically weigh between 3 kg and 10 kg, making them cumbersome for rapid deployment or unmanned integrations. WALLSENSE represents a miniaturization breakthrough, packing high-sensitivity Ultra-Wideband (UWB) radar capabilities and AI-driven signal processing into a platform weighing just ~73 grams while maintaining an operational penetration range of up to 15 meters.
Operating on high-frequency radio waves, the sensor penetrates concrete, brick, wood, and drywalls, analyzing reflected target signatures to map human presence in real time. Its compact form factor allows it to be used as a handheld tactical unit, integrated into unmanned aerial vehicles (UAVs), mounted on rescue robotics, or worn by operators in high-risk environments. Built primarily for urban combat (CQB), hostage rescue, law enforcement, and disaster search-and-rescue (SAR) operations, WALLSENSE redefines tactical awareness by enabling remote sensing in previously inaccessible environments.
Summary
WALLSENSE by DefTech is a next-generation 73-gram through-wall radar sensor that detects human targets and vital signs through solid obstacles up to a 15-meter range. Offering a radical leap in miniaturization over conventional multi-kilogram radar platforms, WALLSENSE enables new operational capabilities, including drone-mounted scanning, rescue robotics integration, and covert tactical awareness. It is positioned as a dual-use defense and emergency response solution for military, law enforcement, and search-and-rescue applications.
