Abstract (en)

[origin: WO2013051944A1] A georadar based on step-frequency, and a method of suppressing interferences (2,3) from other, nearby senders, based on comparing the received signal (1 ) and a filtered estimate of said signal (4). If the deviation for a single frequency fulfills the given criteria (5), the received signal is replaced at this single frequency by a corresponding filtered signal (6,7) at said single frequency.
