<p>The distance measuring method has a transmitter (11) providing a pulsed electromagnetic beam (13) and a receiver (17) for detection of a reflected signal pulse (15), with calculation of the distance of an object (19) from the pulse propagation time The receiver is used for measuring noise with determination of time points at which a receiver threshold is reached and formation of a mean measurement from individual measurements taken at each of these time points. An independent claim for an object distance measuring device is also included.</p> |
