Abstract
Laser active reconnaissance technology is one of the important technologies in the field of optoelectronic countermeasures. However, the Laser active reconnaissance effect is affected by various kinds of factors. According to the process of laser active reconnaissance, the laser active reconnaissance model is established. Furthermore, the echo power and the relationship between the power and various factors are simulated and analyzed. The results show that the echo power is subject to laser divergence angle, atmospheric visibility, angle of incidence and other factors. Among them, the divergence angle has the greatest influence on echo power, followed by the laser incident angle. The slight increase of laser divergence angle and laser incident angle will cause the echo power to drop sharply. However, the slight increase of receiving aperture of cat eye optical window will lead to the echo power increase rapidly. Therefore, in order to obtain the maximum laser echo power in specific application environment, it is necessary to select appropriate parameters for laser active reconnaissance system.
