Abstract

This research indicated the experiment method to analyze and predict the effect of turbulence on the performance of IR thermal imagers. First, the values of structure constant of refractive index, C_n ², were measured. The C_n ² model used in engineering applications is also introduced. And the calculated values were compared to the experiment data, so that the model can be modified. Meanwhile, two IR thermal imagers in MWIR and LWIR bands were installed to provide the data on the range performance. After that, the range values as a function of varying turbulence were calculated utilizing the simulation tool. Finally, this paper analyzed the range values in different groups.
