Development of 24GHz millimeter wave radar for energy-saving in an intelligent street lighting system

Abstract

This paper presents development of 24GHz millimeter wave smart radar for intelligent street lighting system. The developed radar operates at a frequency of 24GHz with 200MHz bandwidth and CW (continuous wave) mode. The two radars are used to cover the street in both directions and detect obstacles moving at the speed of more than 1 km/h including moving pedestrians. The radar detection controls the street lighting. Therefore, the energy-saving performance has been improved because the proposed smart lighting system works only when obstacles around the streetlight exist.
