UWB radar SoC enables 3D beamforming

Hydrogen, an ultra-wideband (UWB) radar SoC from Aria Sensing, delivers 3D MIMO beamforming with programmable pulse bandwidths ranging from 500 MHz to 1.8 GHz. Its advanced waveforms support single-pulse and pulse-compression modes, enabling precise depth perception and spatial resolution. The chip optimizes signal-to-noise ratios for various detection tasks while maintaining low radiated power.

Equipped with two integrated RISC-V microprocessors, Hydrogen accommodates up to four transmitting and four receiving antenna channels with flexible and scalable array configurations to enhance cross-range resolution. Offering 1D, 2D, and 3D sensing, the SoC detects presence, position, vital signs, and gestures, serving automotive, industrial automation, and smart home markets.

“Hydrogen represents a paradigm shift in radar technology, combining cutting-edge UWB advancements with compact SoC design. We are excited to see how this innovation will redefine radar sensing applications,” said Alessio Cacciatori, Aria founder and CEO.

The Hydrogen UWB radar SoC supports multiple center frequencies for global operation without sacrificing resolution. It consumes 90 mA at 1.8 V and is housed in a 9×9-mm QFN64 package.
