Abstract

There has been increasing interest in exploiting the pulsed laser rangefinder (LRF) for military electrical-optics systems. With regard to the LRF for military use, it is very important to gain the constant detective probability. However, the effects of atmospherical optical turbulence can degrade the performance. The irradiance fluctuations, one of the effects of atmospherical optical turbulence, can be a limiting factor for pulsed LRF. In this paper, the effects of the refractive index structure parameter C_n, inner scale l₀, laser wavelength λ and receiver aperture size d_r on the received power scintillation and on the detective probability density of 1.06μm LRF were numerical simulated. The results of our numerical simulation can provide the theoretical considerations for reasonable setting, optimal designing and quantitative testing the system performance specifications of the pulsed LRF.
