In order to create a method for eliminating dummy objects in short-range pulse radar sensors, in which radar pulses are transmitted at a defined frequency, and the time until they are reflected by an object and received again is measured, and besides the transmitted pulse (TX pulse), a delayed second pulse (RX pulse) is generated, which avoids the known disadvantages of the prior art and with which the elimination of dummy objects in short-range pulse radar sensors can be assured, it is provided that the transmitted pulses (TX pulses) and the additionally generated second pulses (RX pulses) delayed relative to them are modulated by a binary phase-shift keying process.
