Abstract
A method for operating an ultrasonic measuring device, encompassing the steps of receiving echo amplitudes, ascertaining object distances for the received echo amplitudes, computing normalized echo amplitudes for the received echo amplitudes, a received echo amplitude with a certain object distance being divided by a reference echo amplitude for the same or a similar object distance, encoding the normalized echo amplitudes, and transmitting the encoded echo amplitudes to a control unit. Also described is a related computer program, a system for carrying out the method, and a vehicle that includes a driving assistance system.
