ABSTRACT:
A method of resolving the frequency ambiguities which result when the instantaneous bandwidth of a digital receiver exceeds the sampling frequency of the digital to analog converter. The frequency ambiguities which result from sampling an input signal below the Nyquist rate are resolved by simultaneously sampling the signal at multiple sample frequencies and then using a lookup table to identify the unique mapping of the common signal into the multiple sample frequency baselines.
