Low Cost K-Band Doppler Radar Sensor For Traffic Control Applications

By Ducommun Inc.

Simple mm-wave CW Doppler technology is used in various applications including automotive speed measurement, liquid flow control, hospital patient surveillance, and intruder detection in security systems. mm-wave technology has progressed quickly, but cost reduction for high-performance sensors using radar technology remains a serious challenge. However, in short-range traffic control applications, cost reduction is possible with a low-cost short-range K-band Doppler radar sensor.
