01 The sensor
Measure speed, direction and motion with 24 GHz Doppler radar.
uRAD Doppler emits a 24 GHz continuous wave (CW) and analyzes its echo to determine target speed and direction in real time — with no cameras, no contact and no moving parts.
It integrates antennas and signal processing on a high-frequency substrate in an 8 grams, ready to connect via UART from day one.

04 Capabilities
Accuracy and direction in every reading.
Four capabilities that define what you can build with uRAD Doppler.
Industrial-grade accuracy
Measure from 8 km/h to 322 km/h with ±0.18 m/s (0.66 km/h) accuracy. Ideal for technical validation, speed monitoring and sports measurement.
Knows whether a target is approaching or moving away
Returns direction and speed in every frame, without extra sensors or external processing to determine movement direction.
Trigger external systems
Two threshold-configurable GPIO outputs can activate signs, alarms or panels when a target exceeds a set speed.
Advanced RAW I/Q data
Extract In-phase and Quadrature signals through the serial port for vibration analysis, micro-displacements or custom signal processing.
05 Applications
Applications for the Doppler radar sensor.
uRAD Doppler is primarily designed for non-contact speed and direction measurement. From that core capability, it can be integrated into technical applications where target motion is the key data point.
Vehicle speed monitoring
Build compact speed monitoring systems for urban and interurban roads. Measure up to 170 m with ±0.18 m/s accuracy, ideal for traffic monitoring and statistics.
170 m range322 km/h±0.18 m/s
Radar speed signs / smart city
Feed driver feedback displays and radar speed signs that show vehicle speed in urban and smart city environments. The two GPIO outputs can be triggered by speed thresholds to activate warning lights or deterrent messages.
Threshold GPIOSpeed feedback signSmart city
Sports speed measurement
Measure speed in training, testing and prototypes. Capture moving objects — balls, athletes or mechanisms — with refresh rates up to 20 samples per second and a range up to 322 km/h.
20 S/s8–322 km/h±0.18 m/s
Technical integration / R&D
Add speed and direction measurement to your own systems using the Python SDK, UART and GPIO outputs. Built for engineers, developers and R&D projects that need real-time motion data — including camera-free motion and presence detection as a secondary use case.
