| Answer | Procedural Description of STK Volumetric Analysis
STK Volumetric Analysis enables you to generate a 3D grid, given some constraints, that is attached to a reference frame. This means that you can adjust the size, shape, and position of the grid, and the position can be dynamic if you use a dynamic reference frame. For example, a grid that is attached to the Body reference frame of a satellite would remain centered on the satellite and would move with the satellite as it orbits. You can also use constraints, such as a sensor line-of-sight constraint, to limit the grids. Once the grid is created, you can conduct calculations that will be evaluated at each grid point. These spatial calculations can include information about the grid point itself or values that are calculated when computing access to that grid point from some other asset in the scenario. When doing calculations based on an access, you can have a hypothetical object “loop” through each grid point and compute access to that object at the grid point. You would want to do this to assign certain properties (such as a Radar Cross Section) and constraints (geometric, lighting, etc.) to your access computation. The Volumetric tutorial online introduces the Volumetric object and various spatial components from Analysis Workbench that model the volume of space covered by a spinning sensor subject to various geometric constraints. |
