I have been manufacturing radar absorbing materials for the past 20+ years. Over the time, I received many inquiries as to whether we could reduce the radar cross section (RCS) of a moving vehicle in such a significant fashion as to reduce the detection range of the speed measuring radars.
The main elements involved in a car’s frontal RCS are:
- The license plate,
- The headlights,
- The vertical metallic surfaces (grill, radiator, engine etc.)
- The driver and anything inside.
As more and more of our market is now in the civilian field (medical and telecom industries), I have decided to do what people have been asking me over the years and check if it is doable to reduce the RCS of my BMW 3-series in a significant way.
I ordered a BMW E92 car bra and I had it fitted with our lightweight, thin X to Ka band RAM. We also have a solution for the air vents. This material absorbs over 15dB (i-e over 95%) of the speed radar energy. In theory, this could translate to a range of detection reduced to up to 50 to 60%.
I might need some assistance to find an appropriate testing area (preferably on the East Coast), ideally a long straight line with little traffic, and a skilled operator with a radar gun.
