Abstract
The invention relates to a method for suppressing an interference signal during detection of a chirp signal from an input signal (X), comprising the following steps: a. recording the input signal (X); b. calculating an output signal (R) as a correlation from the recorded input signal (X) and a chirp reference signal (CR) by means of a correlator (); c. calculating a magnitude (XB) of the input signal (X) from the input signal (X); d. calculating a magnitude (RB) of the output signal (R) from the output signal (R); e. calculating a phase difference (P) between the input signal (X) and the output signal (R); f. calculating a synthesized interference signal (R) from the magnitude (XB) of the input signal (X), the magnitude (RB) of the output signal (R) and the phase difference (P) by means of a rotator (); g. calculating a residual signal (DR) as the difference between the output signal (R) and the synthesized interference signal (R). The invention relates to a system () for suppressing an interference signal during detection of a chirp signal by means of the method according to the invention.
