APPLICATION OF CROSS-CORRELATION TECHNIQUES TO LINEAR ANTENNA ARRAYS

Abstract

The application of cross-correlation techniques to linear antenna arrays is studied. The basic cross-correlation system, which is considered, consists of two linear receiving arrays excited by a distribution of remote radio sources. The terminal voltage of each array is passed through a narrow- band RF filter and the two resulting signals are cross-correlated. It is demonstrated that this system can measure the mutual coherence function of the source distribution. A Fourier analysis shows that the cross-correlation sys tem's output is a filtered version of the mutual coherence function. From this output a three dimensional principal solution can be deduced; it is a generalization of the one-dimensional principal solution given by Bracewell and Roberts in connection with radio astronomy.
