Spectre/Stalcar Mark IV+ vs. radar detectors

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.

Any suggestions?

WilyB:

You’re on the right track. I first tested a radar-attenuating car bra in 1990 and it had a measurable effect on radar range versus this bra-equipped Porsche 911. By 1995 however, the proliferation of Ka-band radar had outstripped the foam’s X/K-only capability.

But with newer materials this is definitely an idea that could be resurrected. Let me know if you need any help with your project.

As you may see in the picture of our remote antenna sleeve, our material is very thin and flexible, but offers -15dB in absorption and close to 100dB in transmission over the X to Ka range.

That url gives an HTTP error 404. Am I missing something or have you an alternate?

It must be a server problem. I tried twice to upload a picture. I will PM you my email address and, if you want, I will email you the relevant pictures.
