Detailed Description
This structure is used to set the model parameters of both 3D Ray Tracing models (IRT, SRT and SBR). This structure can be passed optionally to the WinProp_Predict function. It can be initialized with default values by using WinProp_Structure_Init_Model_RayTracing.
Field Documentation
- SBR_maxTubeArea
-
- double Model_RAYTRACING::SBR_maxTubeArea
- Max side area of the ray tube. If the ray tube area gets larger, the ray will be split. [m]
- SBR_adaptive_maxTubeArea
-
- int Model_RAYTRACING::SBR_adaptive_maxTubeArea
- Adaptive ray density. If higher than zero and an antenna pattern is given, ray density will be lowered globally by the specified number of steps (SBR_maxTubeArea will be divided by 2^steps). In antenna directions with a higher gain the ray density will be increased again up to the user set density into the max gain direction.
