NoteThe limit applies to each individual ray. ## [◆ ](#a36d61fdafa9f1f35f7613a8d7290c9b4)number\_of\_ray\_transmissions int32 vss::simulation::RadarSimulation::number\_of\_ray\_transmissions = 2 The maximum number of transmissions on the scene's objects before the ray is forced to return to the sensor. NoteThe limit applies to each individual ray. ## [◆ ](#aa85ed56a33c422d630d42f3b6c5d5cca)ray\_density double vss::simulation::RadarSimulation::ray\_density = 3 \[deprecated = true\] The linear ray density per radar wavelength (at max distance of 100 m). WarningThis field is marked deprecated and might be removed in later versions. Consider using grid\_sampling instead. ## [◆ ](#a5d6301d6658eaa586d3468a8bc021e2d)grid\_sampling [RadarGridSampling](structvss_1_1simulation_1_1_radar_grid_sampling.xhtml) vss::simulation::RadarSimulation::grid\_sampling = 11 The sampling of the grid. ## [◆ ](#a2eeb1e2e236b79be60d591c578973864)manual\_batching [ManualBatching](structvss_1_1simulation_1_1_manual_batching.xhtml) vss::simulation::RadarSimulation::manual\_batching = 4 ONEOF(batching) The configuration of the manual batching.

When this parameter is set to true, the ego vehicle geometry is considered in calculations upon the emission of the ray's first bounce. When this parameter is set to false (which is the default value), the ego vehicle geometry is not considered in calculations upon the emission of the ray's first bounce. Default value: false ## [◆ ](#aa6929e4d8cb4ad1f48a2994bb8cbcb68)debug\_view\_parameters [RadarDebugViewParameters](structvss_1_1simulation_1_1_radar_debug_view_parameters.xhtml) vss::simulation::RadarSimulation::debug\_view\_parameters = 8 Parameters for the debug view. Optional field. If not set, the debug view is disabled. ## [◆ ](#aee51321ccb1dca97c3ce81d6a7328ff5)max\_ray\_path\_length\_by\_mode map<int32, double> vss::simulation::RadarSimulation::max\_ray\_path\_length\_by\_mode = 9 The maximal length for the ray path per radar mode.
