Abstract

PURPOSE: To automatically identify the various road surface states by detecting the received microwave level reflected on the road surface as transmitted from a microwave transmitter.
CONSTITUTION: A microwave transmitter 5 transmits constant level of a vertically polarized microwave toward the road surface at substantially the same point as the measuring point of an infrared radiation thermometer 4. On the other hand, a microwave receiver 6 is mounted at the position where it receives the microwave regularly reflected on the road surface 1a and transmits the received microwave through a cable 7 to a data processor 8. The data processor 8 utilizes the calculating function of the microprocessor or the like to process the measured temperature and received microwave signal so as to identify the state of the road surface 1a. The identified result is indicated, for example, on an alarm indicator 9.
