Device and method for the suppression of pulsed wireless signals

摘要

The invention relates to a method of suppressing pulsed signals in particular of DME or TACAN type present in the radio signals received (Ue) by a radiofrequency receiver, characterized in that the reception frequency band of the receiver is chopped into frequency sub-bands corresponding to the transmission channels of the pulsed signals, in that the presence of the pulsed signals and the transmission channel of said pulsed signals in the frequency sub-bands are detected, and in that the frequency sub-band comprising the detected pulsed signals is filtered over the duration of the pulsed signal so as to eliminate said pulsed signals pulse type. Applications: protection of GPS or GALILEO type radio receivers against radio disturbances of the DME/TACAN pulse type.
