Abstract: Various technologies described herein pertain to systems and methods for mitigating radar signal power fading. In one embodiment, a diversity of radar sensor units having different vertical positions, or an offset, are provided. The different vertical positions introduce a phase shift to the received radar signal(s) so that when one radar sensor unit is receiving a destructive combination of signals, the other radar sensor unit is receiving a constructive combination of signals. This reduces the effect of signal power fade due to, among other things, ground bounce of radar signals destructively interfering with a radar sensor unit's ability to detect an object.
