3.2.2.3 Use Case – Pedestrian Standing in Empty Parking Space

In this test we use the capabilities of the ultra-short range (0m-10m) sub-frame to detect a pedestrian standing in an empty parking space. The adjacent parking spaces are occupied. The processing chain is configured to perform 3D MIMO detection (azimuth and elevation, 1 Tx enabled at a time) with a maximum range of 10m. The sensor is placed at bumper height at 45 degrees. Testing is performed with both static and moving sensor. The setup is shown in Figure 3-4.

Figure 3-5 shows the point cloud for static detection. The sensor, the car, and pedestrian in the parking space are all static. This is the most challenging detection case.

When there is movement in the scene, the detection is better because Doppler information is used to detect movement.
