Developent Of Radiant Receiving Technology On Laser Beam-Riding Guidance

Due to laser's characteristic of good monochromaticity, good directivity, good coherence and high-brightness, laser guidance technology plays an important role in modern war more and more. In this paper, I have introduced the basic principle of laser beam-riding guidance system, systematically analyzed the influencing factors of laser transmitted in atmosphere, deduced and counted laser power and laser irradiance of unit area that laser receiver received. I have researched decode technology of laser beam-riding guidance, and designed a more digitized laser beam-riding guidance received system scheme, that amplified signal which was generated by photoelectric conversion, then adopted AVR Microcontroller to the signal for frequency selecting and counting, finally obtained information about missile side-play amount. Based on the scheme, we could make the receiver successfully. According to a large number of experiments inside and outside, we can get the conclusion that the system's performance is reliable and high sensitivity.
