ABSTRACT:
An adaptive receiver for determining parameters of an incoming signal is provided. The adaptive receiver includes: a) a plurality of antenna channels; each of the antenna channels including a respective antenna element for receiving the incoming signal and for outputting a respective antenna channel signal; b) a switching matrix operatively coupled to receive antenna channel signals from the antenna channels; the switching matrix for distributing the antenna channel signals to a plurality of receiver channels according to a predetermined mapping; c) a multi-channel down-converter operatively coupled to receive the antenna channel signals from the receiver channels; the multi-channel down-converter for processing the antenna channel signals to output respective intermediate frequency signals; d) a plurality of analog-to-digital converters (ADCs) operatively coupled to receive the intermediate frequency signals from the multi-channel down-converter; the ADCs for converting the intermediate frequency signals to digital signals; the digital signals being indicative of at least the phase and amplitude of the incoming signal; and, e) a digital processor operatively coupled to receive the digital signals from the ADCs for determining the parameters.
