Abstract : The report discusses adaptive arrays in which the reference signal is derived from the array output. A particular problem is studied, the problem of reference loop phase shift. It is shown that phase shift in the reference loop causes the array weights to cycle, and also causes the array to frequency modulate the signal. In spite of this frequency change, the array maintains a maximum SNR at the output. (Author)
