The primary purpose of the report was to fit various techniques and criteria related to optimum array processing into a unified theory. Since the models used were only approximations to the actual physical situation, it is important to understand how various assumptions affect the optimum receiver structure. For an interesting class of criteria and signal models it was found that the optimum receiver consisted of a set of delays to steer the array followed by a combining operation which depended only on the noise covariance matrix. The output of this combiner is a single waveform, which is then processed depending on the criterion and signal model.
