Abstract : The patent concerns apparatus for reducing F sub 1/F sub 1 repeater backscatter without significantly changing the desired received signal. A replica signal of the desired transmitted signal on center frequency F sub 1 is transmitted on center frequency F sub 2 to produce a received signal on frequency F sub 2 which is predominantly due to backscatter from the transmission on F sub 2 and which has a very high correlation with the backscatter from the desired transmitted signal on F sub 1. The characteristics of the backscatter on F sub 2 are accurately measured and then correlated to the backscatter on F sub 1 whereby it can be reduced or minimized with relatively minor change of the desired received signal.
