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.

First claim

What is claimed is:

1. A wideband radio frequency (RF) interference cancellation system, comprising:
an electronic channel canceller configured to split an electronic reference signal output from an electronic transmitting element into a plurality of band signals;
an electronic receiving element configured to receive the electronic reference signal;
a low pass filter, a mid pass filter, and a high pass filter each in electrical communication with the channel canceller, the at…
