Abstract
A procedure for the elimination of interferences of short duration, such as pulses, in a radar unit of the FMCW type where the transmitted and received signals are combined to form a useable signal is provided. According to the procedure, interferences in the useable signal are detected and eliminated in the time domain and the part of the useable signal with interference is reconstructed by extrapolation based on samples without interference. Thus, the occurrence of interferences is prevented in the complex Fourier Transform of the type that is generated by known methods of clipping the signal.
