A Conversation for Automotive Radar
76 GHz clutter returns from water on the road
Claudio Started conversation Sep 11, 2002
When an automotive radar for ACC at 76 GHz is working in a heavy rain weather and there is a layer of water on the road, then there is a well defined clutter return at an angle approximately of -5 degrees from the horizon and constant range.
The data I collected was taken with a vertically polarized radar.
My questions are:
Is there any difference between vertical and horizontal polarization?
Has the Brewster angle have anything to do with this effect?
What could be the doppler of this return?
