Provizio taps TI for single-chip 4D Imaging radar
Irish radar developer Provizio has shown a software-defined antenna reference board built with the AWR2944 sensor from Texas Instruments.
The software-defined antenna increases the radar resolution by more than 20x, balancing the cost and performance challenges of imaging radar.
At the heart of the imaging radar system is the integration of Provizio’s MIMSO software-defined antenna reference design with the TI 77GHz 4D imaging radar chip. This uses the single radar SoC for 48 virtual receiver channels, achieving sub 0.5° angular resolution and enabling precise detection and tracking of objects, including pedestrians, cars, and trucks. Last year TI showed a radar sensor with a new architecture for lower cost implementations.
The reference design is on display at CES 2025 in Las Vegas with a live vehicle demonstration (above).

The MIMSO Software-Defined Antenna Reference Design for Single Chip 77GHz 4D/Imaging Radar is aimed at automotive & industrial OEMs and Tier 1s. By delivering precise, real-time detection and tracking of objects such as pedestrians and vehicles, it enhances a vehicle’s ability to respond to potential hazards. The company has a manufacturing deal with Tier One supplier Mergon.
“We have known for some time that 4D Imaging radar is key to unlocking safer driving and next generation ADAS, however cost has been a key challenge that has held back rollout across all vehicles. This work between Provizio and TI balances the perception and system cost challenges of high-performance imaging radar,” said Barry Lunn, CEO & Co-Founder of Provizio in Shannon.
“To achieve 0.5deg angular resolution using just a single TI radar chip is a testament to the proprietary antenna innovation of the Provizio development team and also the embedded power of the TI radar SoC.”
