This program provides a MATLAB simulation of the correlation interferometer direction finding technique. Utilizing a 5-element circular antenna array as the receiving array, it calculates phase differences between antenna pairs to build a reference pattern library and determines signal direction of arrival through correlation processing. Execute untitled1.m and input relevant parameters to demonstrate the functionality. The implementation includes phase difference computation, covariance matrix generation, and peak detection algorithms for direction estimation.

Digital phase-shift signal generators can produce sine signals at preset frequencies, generate dual-channel same-frequency sine waves with predefined phase differences, and display preset frequency or phase difference values. These devices typically implement Direct Digital Synthesis (DDS) algorithms through FPGA or microcontroller programming, utilizing phase accumulators and lookup tables for precise waveform generation.

This tutorial demonstrates how to perform spectrum analysis using FFT with a practical MATLAB example. The signal_analyzer.rar package contains test data (test1.txt) with time-series input/output signals and a MATLAB script (signal_analyzer.m) that performs FFT analysis to calculate frequency characteristics, amplitude attenuation in dB, and phase differences between signals.
