Accuracy Estimation of a Correlation Interferometric Direction-Finder

Abstract

Using theoretical research and numerical modeling, the parameters of the antenna array of the correlation interferometric direction-finder and its feeder arrangement are revealed in such a way that they can satisfy the required accuracy and the minimal hardware cost. It is shown by theoretical analysis and modeling that non-identical phase frequency responses of the analog receivers used in the direction-finder synthesized by the correlation interferometric approach do not affect the accuracy of the angular estimation.
