@note SW Release Applicability: This tutorial is applicable to modules in both **NVIDIA DriveWorks** and **NVIDIA DRIVE Software** releases.

The following code snippet shows the general structure of a program that uses a Radar sensor.

```{.cpp}
   dwSAL_initialize(...);
   dwSAL_createSensor(...);
   dwSAL_start(...);
   dwRadarScanType scanType;

   for (size_t i = 0; i < static_cast<size_t>(DW_RADAR_RETURN_TYPE_COUNT); ++i) {
       for (size_t j = 0; j < static_cast<size_t>(DW_RADAR_RANGE_COUNT); ++j) {
           scanType.returnType = static_cast<dwRadarReturnType>(i);
           scanType.range = static_cast<dwRadarRange>(j);
           status = dwSensorRadar_readScan(..., scanType, ..., ...);
           dwSensorRadar_returnScan(...);
       }
   }
   dwSensor_stop(...);
   dwSAL_releaseSensor(...);
```
