A method for transmitting data representing an ultrasonic measurement signal of an ultrasonic measuring device, in particular for a vehicle, from a transmitter to a receiver, wherein in the method: - in the transmitter - a digitized analog ultrasonic measurement signal is provided in reaction to an analog ultrasonic transmission signal emitted for detecting obstacles, - the ultrasonic measurement signal is sampled at a multiple of its frequency and divided into individual successive blocks of sampling values, - the sampling values of the sampled ultrasonic measurement signal are transformed in blocks into the frequency range using a segmented fast convolution, - those frequency portions of the spectrum whose amplitude is smaller than a presettable threshold value, or the frequency portions of the spectrum above an upper frequency limit value and/or below a lower frequency limit value are removed, - the amplitude range covered by the remaining frequency spectrum is scaled by a scaling factor for further reduction of the data, and - from the transmitter the data of each block with the scaling factor assigned to the respective block are transmitted to the receiver, and - in the receiver - the scaling of the amplitude range of the frequency spectrum of each block is reversed using the respective scaling factor, - the thus processed frequency spectrum is filtered out of the analog ultrasonic measurement signal provided in the transmitter by multiplication by filter coefficients of an optimum filter for extracting the signal shape of the analog ultrasonic transmission signal, and - the thus filtered frequency spectrum is transformed in blocks back into the time range using an inverse segmented fast convolution. - in the transmitter - a digitized analog ultrasonic measurement signal is provided in reaction to an analog ultrasonic transmission signal emitted for detecting obstacles, - the ultrasonic measurement signal is sampled at a multiple of its frequency and divided into individual successive blocks of sampling values, - the sampling values of the sampled ultrasonic measurement signal are transformed in blocks into the frequency range using a segmented fast convolution, - those frequency portions of the spectrum whose amplitude is smaller than a presettable threshold value, or the frequency portions of the spectrum above an upper frequency limit value and/or below a lower frequency limit value are removed, - the amplitude range covered by the remaining frequency spectrum is scaled by a scaling factor for further reduction of the data, and - a digitized analog ultrasonic measurement signal is provided in reaction to an analog ultrasonic transmission signal emitted for detecting obstacles, - the ultrasonic measurement signal is sampled at a multiple of its frequency and divided into individual successive blocks of sampling values, - the sampling values of the sampled ultrasonic measurement signal are transformed in blocks into the frequency range using a segmented fast convolution, - those frequency portions of the spectrum whose amplitude is smaller than a presettable threshold value, or the frequency portions of the spectrum above an upper frequency limit value and/or below a lower frequency limit value are removed, - the amplitude range covered by the remaining frequency spectrum is scaled by a scaling factor for further reduction of the data, and - from the transmitter the data of each block with the scaling factor assigned to the respective block are transmitted to the receiver, and - in the receiver - the scaling of the amplitude range of the frequency spectrum of each block is reversed using the respective scaling factor, - the thus processed frequency spectrum is filtered out of the analog ultrasonic measurement signal provided in the transmitter by multiplication by filter coefficients of an optimum filter for extracting the signal shape of the analog ultrasonic transmission signal, and - the thus filtered frequency spectrum is transformed in blocks back into the time range using an inverse segmented fast convolution. - the scaling of the amplitude range of the frequency spectrum of each block is reversed using the respective scaling factor, - the thus processed frequency spectrum is filtered out of the analog ultrasonic measurement signal provided in the transmitter by multiplication by filter coefficients of an optimum filter for extracting the signal shape of the analog ultrasonic transmission signal, and - the thus filtered frequency spectrum is transformed in blocks back into the time range using an inverse segmented fast convolution.
