Damage capability of laser system in ground-air defense environments

A comprehensive model is proposed to evaluate the damage capability of laser system in ground-air defense environments. This model takes into account the laser system’s heavy reliance on weather conditions and the stringent requirements for beam pointing accuracy. It initiates by simulating the laser spot characteristics on target in ground-to-air environments, factoring in the effects of atmospheric turbulence, absorption and scattering through slant transmission paths. Subsequently, a calculation method based on the thermal damage effect of the target material is introduced to quantify the damage ability of the laser system. To further enhance the model’s applicability, a method for calculating the laser damage probability based on random crossover theory has been introduced, which takes into account the error of the Acquisition, Tracking and Pointing (ATP) system to estimate the likelihood of successful damage in operation applications. Theoretical analysis and simulation results validate the effectiveness of the proposed model in calculating and analyzing the damage capability of laser system in ground-air defense environments. This model offers valuable decision-making insights for users of laser systems operating in low-altitude atmospheric conditions. Furthermore, it furnishes essential data support for the development and validation of laser systems, ensuring their effectiveness in real-world applications.
