We have shown the role of coherence in waveform design in determining the performance of a sensing system by incorporating the degrees of freedom afforded by new waveform design strategies. Using this approach, we were able to use coherence properties generated by the waveform and aperture to derive an analytic bound on the Generalized Likelihood ratio test that is commonly used in many sensor systems. Thus coherence allows a means of determining a fundamental bound on system performance.
