Abstract:
1. A receiver, comprising: a signal generator configured to generate a plurality of ramped signals, having continually varying frequency ramps, and to provide one of the plurality of ramped signals to a transmit antenna; a receive antenna port configured to receive a reflected signal, comprising a time shifted version of the one of the plurality of ramped signals that is reflected off of an object that is external to the receiver, and to provide the reflected signal to a receiver chain; a memory element configured to store compensation parameters corresponding to the plurality of ramped signals; and a signal correction element arranged within a feedback path extending between points in the receiver chain and configured to generate a correction signal that is provided to the receiver chain, that reduces unwanted signal components in the reflected signal, based upon stored compensation parameters corresponding to the one of the plurality of the ramped signals.
