Houston Radar’s SS300ULG Ultra Low Speed Doppler sensor/Doppler Radar is a state of the art milli-power Digital Signal Processing (DSP) based K-band radar for close up non-contact speed measurements and other industrial and security applications requiring high resolution short range speed measurement or motion sensing to large targets. It is the premier product in its class available in the world.
SS300ULG Open Frame
SS300ULG Weather Proof
- World’s smallest and low power usage OEM K-Band Ultra low speed Doppler radar at 0.25 Watts, up to 25X lower than some other industry offerings
- Designed for up close measurements to large objects such as trains
- Measure speeds down to 0.13mph (0.2kph) and up to 11mph (18kph)
- High resolution ASCII speed output with 3 places of decimal (0.001mph internal resolution)
- Continuous measurement with sliding window output update to maximize signal quality
- User specified IIR filter time constant on measurement data to prevent output speed jumping
- User specified output decimation value to control output speed update rate
- Support for mph, kph, fps and mps speed units
- FCC pre-approved with CE mark
- Fully configurable via RS232 serial port for all settings
