Abstract
The Battlefield Environment Weapon System Simulation (BEWSS) includes battlefield obscurant transport and diffusion models and adverse weather models which can predict transmission over a specified range in the presence of specified meteorological (MET) conditions, obscurant conditions, and scenario geometry. These models are used to generate transmission maps applicable for a particular sensor boresight, resolution, field-of-view (FOV), and spectral bandwidth. In addition, a three-dimensional IR target/background scene is modeled, and perspective views of the target are generated from any viewing geometry. By combining the BEWSS obscurant models with the target/background model, realistic synthetic imagery of an obscured tactical target is generated for use in analyzing night sights and IR seeker/trackers. The unique feature of these images is that they are correlatable to a particular set of assumptions about the target/background temperature, the MET conditions, the obscurant conditions and the IR sensor characteristics. The imagery is displayed on an IRIS 4D-GT Silicon Graphics workstation, and the high-resolution thermal maps are stored for future analysis. The imagery has been animated and stored in video format for use in evaluating seeker/tracker terminal homing performance. This paper presents the BEWSS models employed in developing the computational algorithm, and displays examples of the generated imagery.
