The sensor measures relative motion - point it at what you want to measure. Either the sensor or the target may be moving - or both simultaneously. The sensor may be used to measure the speed of a surface such as the ground.
Non-contact sensing means that the sensor measures only the true relative motion of the target. For vehicle ground speeds, wheel slip is no longer an issue. For conveyor belts, the actual speed of product can be measured. For amusement park rides, the support structure can act as a target.
The sensor can be used for quick, portable measurements or it can be mounted permanently to monitor a single lane of a highway as part of a complete monitoring system. Multiple sensors placed on an overhead structure such as a signpost or overpass can be used to give a complete picture of traffic flow by lane in a given location.
Traffic Monitoring
The Doppler Radar Speed Sensor can be used in many different traffic monitoring situations to give vehicle speeds and counts. It can also be used to give estimates of vehicle length which can be used in classifying traffic flow by vehicle type.
Amusement Park
Perhaps one of the most demanding applications of the Doppler Radar Speed Sensor is in amusement park ride testing.
