1. A compound receiver of a plurality propagating signals, comprising:
a monitor receiver for receiving the propagating signals, the monitor receiver for generating a monitored electrical signal representing the propagating signals;
a filter for generating a filtered electrical signal representing at least one selected propagating signal isolated from the propagating signals represented within the monitored electrical signal;
a transmitter for retransmitting, with a specified timing, said at least one selected propagating signal represented within the filtered electrical signal;
a protected receiver for receiving a combination of the propagating signals and said at least one selected propagating signal retransmitted from the transmitter, the protected receiver generating a detected electrical signal representing the combination; and
a relative position sensor for adjusting the specified timing to suppress said at least one selected propagating signal represented within the detected electrical signal.
