New optical modulation schemes applied to local oscillator distribution in radar systems
An original heterodyne modulation scheme is presented for generating tunable local oscillator signals. A dual-frequency laser has been cascaded with a frequency shifters to down or up convert RF signals in the range 0.2-32 GHz.
