BSP step for on-ground targets RCS measuring or calculation

Currently, an important issue is the evaluation of radar visibility of different complex objects. To achieve this goal it is necessary to receive the BSP for the test object. However, the BSP calculation usually takes most of the time necessary for a comprehensive assessment of radar visibility of the object. In this article we will look at angle step choosing in BSP calculations for objects situated on some underlying surface. For step choosing statistical analysis approach was used.
