Guidance weapon is playing an increasingly important role in modern war.In this paper,the fundamental theory of the laser beam-riding guidance instrument was introduced.A 10.6 μm laser code modulator using CO2 laser as laser radiation source was designed,which was used to control the high-speed aircraft.Utilizing frequency-coded modulation technique,coding method and optical coded modulation disk were proposed in order to satisfy the parameters of the guidance system.Based on the calculation on mathematics model of the off-center of the missile and the requirements of guidance control,reasonable coded frequencies were obtained.In order to satisfy the application requirement of the guidance system,the width and the quantity of the gratings in the modulator were obtained according to the frequency and dimension of the modulated disk.Each parameter was reasonably designed and capable of meeting the precision requirement of the guidance instrument.Based on a large number of experiments inside and outside,it is concluded that the system′s performance was reliable and highly sensitive.
