Abstract :
Several concepts and formulae are presented that are useful in the examination of the signal-to-noise performance of phased array antennas with dissimilar signal paths or subarray sizes. It is demonstrated that, in most such cases, aperture illumination efficiency remains an accurate indication of array antenna noise performance
