摘要:
The invention relates to a method for detecting target echoes (11) in a reception signal (ES) of an ultrasonic sensor of a motor vehicle by providing a reference signal (RS) for decoding the reception signal (ES), wherein with respect to a multiplicity of predetermined frequency shift values in each case a correlation input signal (RS) is provided by shifting the reference signal (RS) in terms of its frequency by the respective frequency shift value; correlating the reception signal (ES) separately with each of the correlation input signals (RS) and thereby providing respective correlation output signals (KS1 to KS7), as the result of the respective correlation; and by providing a summation signal (SS) as the sum of the correlation output signals (KS1 to KS7), wherein on the basis of the summation signal (SS) one of the correlation output signals (KS1 to KS7) is selected and detecting the target echoes (11) is carried out by evaluating the selected correlation output signal (KS1 to KS7).
