zSIGNAL brings high quality 4D imaging radar to all platforms. Developed for low-cost, scalable deployment.

Compact versatility

Smaller than a sticky note and weighing just 125 grams, zSIGNAL's configurability and size allows it to be used in any application, including autonomy, robotics, and heavy equipment

Powered by SDIR

zSIGNAL leverages our full SDIR processing pipeline to implement a cutting-edge, flexible radar imaging pipeline. SDIR provides the performance and flexibility for zSIGNAL to work optimally in both indoor and outdoor environments.
