Method of decoying of a system for interception and/or jamming, consisting in generating, in a signal to be emitted, a dummy sequence (SYNCF), said method comprising the following steps: - defining said dummy sequence (SYNCF) and its temporal and/or frequential position within the signal to be emitted, the values of the symbols of said dummy sequence and their temporal and/or frequential positions being different from those of the symbols of a synchronization sequence (SYNC) that the said signal comprises, - estimating the value and the position of the dummy bits (BF) to be inserted within the data sequence (Du, T) to be emitted at the input of the emission chain so as to obtain, in the sequence produced at the output of the emission chain, the predetermined value and predetermined temporal position of the symbols of said dummy sequence (SYNCF), - inserting, within said data sequence (Du, T), the dummy bits (BF) at the positions obtained. |
