FMCW and Chaotic Microwave Generation Using Nonlinear Photonic Systems for V- and W-Band Radar Applications
Abstract
Radar schemes using frequency-modulated continuous-wave (FMCW) microwaves and chaotic microwaves, respectively, are highly attractive as they provide high range resolution, strong anti-jamming capability, high noise immunity, simple system structure, high signal-to-noise ratio, large dynamic range, and high measurement accuracy, stability, and sensitivity. These advantageous performance characteristics are attributed to their unique temporal and spectral microwave features. In this project, two novel photonic approaches based on nonlinear dynamics of semiconductor lasers are proposed and investigated to generate FMCW microwaves and chaotic microwaves, respectively, for better radar performance characteristics, such as broader modulation bandwidth for better resolution in longitudinal direction (i.e., range resolution), higher carrier frequency for better resolution in transverse direction (i.e., cross resolution), stronger anti-jamming capability, and higher noise immunity.
