1. A method for performing sensor control for a signal processing system, comprising:
receiving at least one signal from at least one remote source;
determining motion of at least a portion of the signal processing system;
correlating at least one local signal with the at least one received signal to generate at least one correlation result;
motion compensating the at least one local signal, the at least one received signal or the at least one correlation result using the determined motion to produce at least one motion compensated correlation result;
compensating a phase evolution of at least one of the at least one local signal, the at least one received signal and the at least one motion compensated correlation result based on a plurality of hypotheses regarding at least one sensor parameter of at least one sensor to generate at least one phase-compensated correlation result;
determining a preferred hypothesis in the plurality of hypotheses that maximizes the at least one phase compensated correlation result, wherein the determining the preferred hypothesis further comprises combining a plurality of phase compensated correlation results to generate a joint score and determining the preferred hypothesis associated with a highest joint score; and
adjusting the at least one sensor parameter to conform to the determined preferred hypothesis.
