Research on laser coding technology based on signal generator

Aiming at the main coding mode of laser guidance signal,the realization method of producing specific coding based on general signal generator was studied.According to the characteristics of laser coding,the laser coding control program was designed,and the generation of three main laser coding methods was realized successfully,including precise frequency code,pulse modulation code,random time code.Finally,the laser coding experiment was carried out.The laser pulse was modulated by outer triggering mode of the laser coding control program,so the target laser was required to output a specific coded laser signal.The results show that,the laser code waveform generated by this method is stable,excellent performance and strong applicability.The technology has been successfully applied to the laser guidance hardware-in-the-loop simulation experiment system.
