Study on the influence of different numbers of array elements on direction finding performance

In modern wireless communications and radar systems, accurate direction finding technology is crucial for signal processing and positioning applications. This paper deeply explores the impact of the number of array elements and aperture size on direction finding performance, aiming to provide a theoretical basis for antenna array design. By establishing antenna array models of different uniform circular arrays, their direction finding accuracy is analyzed. Finally, simulation experiments are performed to verify the correctness of the theoretical analysis.
