Abstract
A radio frequency transmission and reception system, for use as an active decoy, includes a receiver 10, a transmitter 12 and a signal generator 20 for providing wideband noise signals for transmission during the interpulse period of pulsed signals transmitted by the transmitter 12. A feedback circuit 21, including an adaptive transversal filter 23 combines signals for transmission with output signals from the receiver to adaptively modify the wideband signals in the signals for transmission so as to render the receiver 10 substantially insensitive to received signals which are derived from the transmitter.
