Frequently Asked Questions (FAQ)
What is the uRAD Doppler v1.0?
The uRAD Doppler v1.0 is a professional 24 GHz radar sensor designed to measure the speed of moving objects with high accuracy. It uses Doppler CW (continuous wave) technology to deliver reliable, non-contact measurements even under low-visibility or dusty conditions.
How are the radar parameters configured?
Configuration is done through commands. UART.
The adjustable parameters include:
-
Minimum and maximum detectable speed (8 – 322 km/h).
-
Sensitivity (10 levels).
-
Positive/negative speed thresholds for GPIO.
-
Sampling rate (4, 10, or 20 samples/s).
-
Installation angle correction (up to 45°).
What is the maximum speed the uRAD Doppler radar can measure?
The radar detects speeds of up to ±90 m/s (322 km/h) with an accuracy of ±0.18 m/s (0.66 km/h). It is ideal for traffic control, sports, industrial safety, and IoT applications.
How is the uRAD Doppler connected to other devices?
It communicates via UART (0–3.3 V), allowing integration with Raspberry Pi, microcontrollers, or systems running Windows, Linux, macOS, and Android. It includes a Python SDK with practical examples and a graphical interface (GUI) for real-time visualization and CSV data storage.
How is the uRAD Doppler powered?
It operates with 3.5 – 6 V DC (5 V recommended) and a typical power consumption of 137 mA (~0.7 W).
It uses a JST B7B-XH-A (1×7P 2.5 mm) connector.
It uses a JST B7B-XH-A (1×7P 2.5 mm) connector.
What data output does the radar provide?
The radar provides:
-
Positive and negative velocities (objects moving away or approaching).
-
Raw I/Q data (phase and quadrature) for custom processing.
-
Digital GPIO signals configurable as speed alarms.
The data can be visualized or stored in CSV files using the Python SDK or the included GUI.
How many objects can it detect simultaneously?
The radar can simultaneously detect objects moving in both directions (approaching and receding).
If it detects multiple objects moving in the same direction, it returns the speed of the target with the highest reflected signal amplitude, i.e., the most dominant one.
If it detects multiple objects moving in the same direction, it returns the speed of the target with the highest reflected signal amplitude, i.e., the most dominant one.
Is it possible to access the raw signal data (RAW I/Q)?
Yes. The RAW DATA mode allows direct acquisition of phase (I) and quadrature (Q) data, making it ideal for developers who want to apply custom signal processing, filtering, FFT, or multipath detection.
What precautions should be taken during installation?
The antenna must not be covered with metallic or electromagnetic-absorbing materials, as they block the radar signal. Thin plastics, however, are transparent to the emission and can be used as physical protection.
