2002 NVTherm improvements
The Windows version of the Night Vision Thermal Imaging System Performance Model, NVTherm, was released in March 2001. NVTherm provides accurate predictions of sensor performance for both well-sampled and undersampled thermal imagers. Since its initial fielding in March 2001, a number of improvements have been implemented. The most significant improvements are: (1) the addition of atmospheric turbulence blurring effects, (2) National Imagery Interpretability Rating System (NIIRS) estimates, (3) and the option for slant-path MODTRAN transmission. This paper presents these modifications, as well as a brief description of some of the minor changes and improvements that have been completed over the past year. These significant changes were released in January 2002
