MATLAB Simulation of Correlation Interferometer Direction Finding Method

This program implements a MATLAB simulation of the correlation interferometer direction finding method. The algorithm employs a 5-element circular antenna array configuration as the receiving array, computes phase differences between antenna element pairs to establish a reference pattern database, and determines the signal's direction of arrival through cross-correlation analysis. Users can execute the main script untitled1.m and input relevant parameters to activate the functionality. The simulation helps researchers deeply understand the working principles of correlation interferometers and enhances practical applications. Key computational steps include: 1) Phase difference calculation using angle estimation algorithms 2) Generation of covariance matrices from received signals 3) Pattern matching through correlation processing. For instance, this method can be applied to radio telescope data processing in astronomy to precisely determine celestial positions and motion states. Additionally, the program can be adapted for signal processing research in other domains such as acoustic wave and electromagnetic wave analysis.
