Abstract: A feed-forward cancellation system includes a transmitting element and a receiving element. The transmitting element is in electrical communication with a transmitting line. The transmitting element is configured output a transmission signal to the transmitting line. The receiving element is in electrical communication with a receiving line. The receiving element is configured to process a response signal that is generated in response to the transmission signal and that is delivered to the receiving line. At least one antenna is configured to transmit the transmission signal, receive the response signal generated based on the transmission signal, and deliver the response signal to the receiving line. The feed-forward cancellation system further includes an electronic cancellation unit configured to generate a cancellation signal based on the transmission signal. The cancellation signal eliminates saturation from at least one of the response signal and the receiving line.

Abstract: A wideband radio frequency (RF) interference cancellation system includes an electronic channel canceller configured to split an electronic reference signal output from an electronic transmitting element into a plurality of band signals. At least one electronic band pass filter is configured to receive a respective band signal delivered to a respective channel. The wideband RF interference cancellation system further includes at least one electronic tunable cancellation element configured to tune the respective channel such that reflections are canceled before being input to receiving element.
