4D tracking sensor for mobile ITS

Radar sensor developer 8150 Oculii has launched the RFS-M, which it claims is the first real time 4D tracking sensor designed for mobile platforms. The K-Band RFS-M is embedded with IMU and GPS sensors, enabling it to be rotation and motion invariant and making it suitable for mobile ITS and enforcement applications, as well as autonomous vehicle sensor platforms.

The sensor’s 4D technology enables it to maintain target tracks, even when there is zero doppler, for mobile applications in which the doppler signature of targets relative to the platform will be positive, negative or zero. The internal IMU and GPS supplement internal tracking state vectors to remove any transient sources of platform ego-motion, to stabilise target-tracking data. Oculii's 4D radar provides (X, Y, Z) coordinates, range, range-rate, azimuth and elevation angles in real time at an update rate of 20Hz.
