1. A method for detecting a degradation in a distance-measuring system, the method comprising:
transmitting a transmission signal;
acquiring a received signal back-scattered from an object;
determining a distance from the object based on a transmission time of the received signal;
determining a degree of degradation of the distance-measuring system based on at least one of the determined distance from the object or a received signal strength of the received signal; and
averaging multiple measurement points of the distance or of the received signal strength, and using average values of the distance or of the received signal strength to determine the degree of degradation.
