Velocity in Every Voxel – Perception in Robotics
A new 4D imaging radar technology allows for real-time measurement of both position and velocity without the need for frame-to-frame comparisons. This advancement is crucial for robotics operating in dynamic environments with moving objects. The technology utilizes a combination of multiple antennas and advanced signal processing to create a detailed four-dimensional representation of the surroundings.
- ▪The 4D imaging radar reports velocity and position simultaneously, eliminating the need for tracking across frames.
- ▪This technology uses a MIMO setup to enhance angular resolution significantly compared to traditional systems.
- ▪Arbe Robotics has developed a radar with 2,304 virtual channels, providing high precision for automotive applications.

Velocity in Every VoxelMonday, May 25, 2026 · PerceptionJaiminMay 25, 2026ShareA stereo camera pair can tell you a mug is sitting on the edge of a table. It cannot tell you the mug is sliding off, or how fast, until it has compared two frames and worked out the difference. A 4D imaging radar reports the velocity in the same shot that reports the position. Every point it returns carries range, azimuth, elevation, and a Doppler-derived radial velocity from a single burst of radio waves, no frame-to-frame stitching required. Friday closed with a promise about the radar lane.
