Abstract
A compound receiver receives radio-frequency electromagnetic or other propagating radiation. A filter generates a filtered electrical signal representing at least one selected electromagnetic signal isolated from a monitored electrical signal. A transmitter retransmits, with a specified timing, the selected electromagnetic signal or signals represented within the filtered electrical signal. A protected receiver receives a combination of the electromagnetic signals and the selected electromagnetic signal or signals retransmitted from the transmitter. The protected receiver generates a detected electrical signal representing the combination. A relative position sensor adjusts the specified timing to suppress or cancel the selected electromagnetic signal or signals represented within the detected electrical signal.
