Abstract:

LONG TERM GOALS. The long-term goals of the research are to understand and assess the effects of the atmosphere on the detection of targets at low altitudes over sea in coastal regions with LR-IRST systems. Effects considered are transmission losses due to aerosols and water vapor, effects of turbulent fluctuations of the air temperature on blurring and scintillation, and the effect of the vertical temperature gradients on IR refractivity. OBJECTIVES. The objectives of the research performed in the framework of the present grant are to further analyze and validate results obtained in the EOPACE experiments on the Californian coast, in particular to validate the aerosol source function in the surf zone to quantify the effect of the surf zone on the aerosol concentrations in the coastal atmosphere, in relation to surface-produced sea spray aerosol and anthropogenic aerosol to determine the turbulence and refractivity in the inhomogeneous coastal boundary layer and their effects on imaging of low altitude point targets to improve the description of the aerosol size distribution as function of height and meteorological parameters.
