More Information
Summary:A radar receiver includes an analogue receiver for receiving a radar echo signal and a digital receiver. The digital receiver includes an analogue-to-digital converter arranged to receive and sample an IF analogue signal from the analogue receiver. The sampling is undersampling according to the Nyquist criterion, so that a plurality of IF digital signals are produced, in different Nyquist zones, including one or more aliased IF digital signals. The digital receiver is arranged to select an IF digital signal from the one or more aliased digital signals.
