<p>A method and system for generating single and multichannel optical analog pulse-frequency modulation waveforms are disclosed. The system comprises a frequency modulator (506), a continuous wave optical source (514), and an optical modulator (516). The frequency modulator (506) receives the analog signal (504) and converts the analog signal into a frequency modulated signal (512). The optical modulator (516) modulates the continuous wave optical source (514) with the frequency modulated signal (512), to produce the optical pulse-frequency modulation signal (520). The method comprises converting (1200) an analog input signal into a frequency modulated signal, amplifying (1202) the frequency modulated signal (512) and producing a large signal therein, modulating (1204) a continuous wave optical source with the large signal, therein producing the optical pulse-frequency modulation signal (520), and compressing (1206) the optical pulse-frequency modulation signal (520), therein increasing a processing gain. <IMAGE></p> |
