Modelling studies of transmission and scattering of high energy laser radiation under remote continental conditions

摘要: A numerical model is developed to simulate the angle dependent light scattering. The based on Mie theory and uses complex refractive indices of aerosol particles rain droplets together with their corresponding experimental number size distributions as input parameters. laser beam parameters high energy at DLR transmission test range in Lampoldshausen geometry detection system are taken into consideration. It demonstrated that accurately predicts absolute scattered powers obtained by a calibrated multiangle scattering probe measuring under five different angles. applicable for dry rainy weather conditions. In addition, calculations performed determine extinction coefficients 1030 nm. calculated correlated meteorological (i.e. rainfall intensity visibility) from types instruments. compared derived experiments good agreement between results measurements observed conditions.
