RF Photonics for Radar Front-Ends

Abstract

Recent developments in RF photonic component technologies can have a significant impact on future radar system architectures. In this paper, current performance of low noise figure and high dynamic range RF distribution links and delay lines, low phase noise RF oscillators, and fast tunable RF filters developed using photonic technologies are highlighted. Performance comparisons with electronic RF front-end technologies are provided including size, weight and power considerations. Finally, other RF photonic technologies applicable to radar systems and further photonic device improvements required for more pervasive radar system use are discussed.
