GPS GPS REFLECTED WAVE ANALYSIS SYSTEM FOR ROAD SURFACE FREEZE DETECTION

摘要

Disclosed is a GPS reflected wave measuring and analyzing system for detecting road surface. The present disclosure provides a GPS reflected wave analyzing system for minimizing multipath effects and signal noise patterns. Specifically, by measuring the signal strength and phase by the microwave GPS reflected wave and analyzing measured data, various surface media information caused by various physical properties of the surface can be accurately grasped.
