Claim:
1. A feed-forward cancellation system, comprising: a transmitting element constructed as a high power amplifier that is in electrical communication with a transmitting line, the high-power transmitting element configured to output a high-power transmission signal to the transmitting line; a receiving element in electrical communication with a receiving line, the receiving element configured to process a high-power response signal that is generated in response to the high-power transmission signal and delivered to the receiving line; at least one antenna configured to perform at least one of: transmit the high-power transmission signal, receive the high-power response signal generated based on the high-power transmission signal, and deliver the high-power response signal to the receiving line, wherein the at least one antenna includes: an electronic cancellation unit interposed between the first antenna and the second antenna, the electronic cancellation unit including a digital signal processor configured to generate an electrical cancellation signal based on the high-power transmission signal, and injects the cancellation signal upstream from the receiving element so to eliminate saturation from at least one of the high-power response signal and the receiving line,
