Figure 4. Left: direct path return; right: multipath return

Multipathing occurs when a large ﬂat surface near the sensor inter-

feres with detection. A radar signal can bounce around several

times between the surface and the vehicles before returning to the

sensor. This can make the sensor detect a vehicle where there is

none.

This can happen with
