1. An antenna array adaptive signal processor for improving the signal-to-noise ratio of a received signal containing a direct component and multipath components in an unknown electromagnetic environment comprising:

  • signal conducting means for carrying a plurality of signals from antenna elements along a plurality of preselected paths,filter means connected between said array signal and each of said signal conducting means to minimize the mean square error of said array signal as compared with a reference signal, whereby said array signal is formed in a selected look direction, andadaptive channel estimating means for generating said reference signal so that said reference signal includes the direct component as well as the multipath components of the received signal.
