Speed Monitoring

Product Summary

Traditional techniques monitoring the spinning of wheels etc. creating inaccurate speed measurements. The “AT-SOG75-1111-P” speed over ground radar is designed to be mounted on the vehicle itself. 

General Description

This Attingimus radar unit mounted on a vehicle will provide accurate speed measurement.  Every 10 ms the radar can issue speed and direction data. The speed over ground corresponds with a pulse frequency rate. Filtering on signal strength and distance to the radar makes this a very robust speed measurement radar.

Every meter of travel distance corresponds to 16 pulses. This is a default value which is configurable by Attingimus or the customer. The pulses have a 50% duty cycle.  The height of the pulses in volt equals the supply voltage. By measuring only the Doppler and therefore speeds at a specific range, reliable speed measurements are assured. A relatively small speed can already be measured; the minimum speed is 10 cm per second.
