The Research Of Back-reflected Laser From Infrared Seeker

The infrared missile tracking system with laser is the important technology of airorne laser system. The feature of backeflected laser from infrared missile is core content in this technology. The research object of this paper is PL? infrared missile. In this paper, the produced principle of backeflected laser is discussed and the kind of backeflected laser that can be used in reality accept is defined. According to the numerical calculation, the reflection efficiency of backeflected laser from infrared missile with different convey distance weather wavelength is founded. The relation which intensity distribution of backeflected laser with reflected distance and reflected laser stain radius is obtained. The experiment system is designed. The result of experiment proved the numerical calculation.
