Optical samples of RF signals are all-optically parallelized for further processing in low-speed electrical digitizers. This technique enables high-rate sampling with no additional jitter and limited ...
Nonlinear scattering at HF: Prospects for exploitation in OTH radar systems
Nonlinear scattering nonlinear transfer function Volterra expansion rusty bolt HF radar OTH radar HFSWR
