Abstract
A method for detecting a degradation in a distance-measuring system (1.1), comprising the following method steps: transmitting a transmission signal (1.2), acquiring a received signal back-scattered from an object, determining the distance (a) from the object using the received signal, and determining a degree of degradation based on the determined distance (a) from the object and/or the received signal strength of the received signal.
Claims14
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.
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;
- and
- 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,
- wherein the degree of degradation is determined based on both the determined distance from the object and the received signal strength of the received signal, and wherein a plausibility check is provided in order to verify the determined degrees of degradation using the determined distance from the object and the received signal strength of the received signal relative to one another.
A distance-measuring system for determining distance, the system comprising:
- a transmission unit configured to transmit a transmission signal;
- a receiving unit configured to acquire a received signal back-scattered from an object;
- and
- a processor configured to:
- determine a distance from the object based on a transmission time of the received signal,
- determine 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
- average multiple measurement points of the distance or of the received signal strength, and use average values of the distance or of the received signal strength to determine the degree of degradation.
