Abstract:

This report summarizes a quantitative analysis of the effects of random gain and phase errors and angular variations on the performance of a class of Least-Mean-Square LMS optimal array processors. Two different structures for the LMS optimal array processor were studied. Both belong to a general class of side-lobe cancelling arrays and both structures employed a conventional beamformer as an integral part of the structure. The first implemented a linear constraint using software and the second employed a simple spatial hardware preprocessor to implement the same constraint. An analysis of the sensitivity of both LMS optimal array processors as well as a conventional beamformer to random gain and phase errors was performed.
