New robust threshold setting method for frequency-hopping acquisition

A new, very robust threshold setting method for the serial search acquisition of frequency hopping (FH) waveforms, the ´reference channel detector´ (RCD), is proposed and analysed. It is shown that this detector has considerable immunity when subjected to large signal dynamics and pulse jamming. Especially in pulse jamming, this procedure is a much more appropriate solution than the constant and adaptive threshold setting methods reported previously.
