3.2.2.2 Use Case – Traffic Cone, Grocery Cart, Sign Pole, Pipe, Shrub

In this test, we use the capabilities of the ultra-short range (0m-10m) sub-frame to detect traffic cones, grocery carts, sign poles, pipes, and shrubs. 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. We perform tests at boresight and at 45 degrees angle. The sensor is placed at bumper height and it is static.

Table 3-3 and Table 3-4 summarize the results.

Figure 3-2 shows a traffic sign pole used for testing. For this test we wanted to emphasize the detection in elevation.

Figure 3-3 shows the elevation view of the traffic sign pole.
