Frequency Diverse Phased Arrays

Abstract

This article introduces what frequency diverse array (FDA) is and why it could be utilized in radar and wireless communication systems for improved performance. Recent advances and potential applications together with the technical challenges are discussed. It is shown that FDA indeed provides promising potential for future radar, communications, and even integrated radar and communication applications. However, for practical applications further work on system implementation, optimal array signal processing, and time‐variance related problems should be carried out.
