A Phased Array Maintenance Monitoring System. Part I.

Abstract

Two methods are described for detecting failures in a phased array through the use of an integral r-f maintenance monitor system. Both methods use an r-f sampling manifold located at the radiating aperture. The methods represented are not exhaustive and are intended as examples. The first method, the balanced monitoring system, requires an adjustment network for zeroing the initial reading, while the second method, Fourier transform system, requires a Fourier transformation computation. Results of computer simulation of these two methods are presented. This is the first part of this report which treats only a conventional phased array. An array using COMPACT network will be discussed in part 2 of this report. (Author)
