Stalker Sensors

A radar speed sensor uses Doppler radar technology to measure the speed of moving objects without physical contact. It transmits radio waves and calculates speed by analyzing the reflected signal. Radar speed sensors are widely used for traffic monitoring, railroad safety, waterflow measurement, industrial automation, and OEM applications because they provide accurate, real-time speed data in a variety of environments.

Surface Velocity Radar uses Doppler radar technology to measure the speed of a moving surface without physical contact. The sensor transmits radio waves, receives the reflected signal and calculates velocity from the change in frequency.

Radar speed sensors use Doppler radar technology to measure the true ground speed of a moving railcar or train. Unlike wheel-based sensors, they do not require physical contact with the axle or wheels. By continuously transmitting and receiving radio waves, the sensor calculates speed in real time and provides accurate motion data for railroad automation, yard control, and safety systems.

LiDAR (Light Detection and Ranging) speed measurement uses laser pulses to determine the speed and distance of a target with exceptional precision. Compared to radar, LiDAR provides a narrower beam for highly targeted measurements, making it ideal for traffic enforcement, school zones, work zones, wrong-way detection, and other applications where pinpoint accuracy is required.

Radar speed sensors are highly accurate and designed to deliver consistent speed measurements across a wide range of applications. They excel at measuring both high-speed and low-speed targets, making them suitable for traffic monitoring, railroad operations, industrial equipment, and water velocity measurement. Accuracy depends on the specific sensor model, installation, and operating environment.

Yes. Radar sensors are designed to operate reliably in challenging environmental conditions, including rain, snow, dust, fog, vibration, and low-light environments. Because radar uses radio waves rather than visible light, it maintains dependable performance in conditions that can limit optical or camera-based systems.

Radar speed sensors are used across many industries that require accurate, non-contact speed measurement. Common applications include traffic engineering, law enforcement, intelligent transportation systems, railroad safety, water resource management, mining, agriculture, industrial automation, and OEM equipment manufacturing.
