Fractals reduce scattering of radar reflections for driverless cars

Fractal Antenna Systems has developed solutions to make road tags brighter to vehicular radar, for improved driverless tracking, and enabling the antiquation of LIDAR systems. The solutions also enable unique advantages for future flying cars/taxis, and even satellites.

The new patented and patent pending technology while reducing the reflected “scattering” to a radar signal, FRACTAL not only found a way to make the reflections disappear, but also found other unique fractal-based solutions that actually enhanced radar reflection. Such unusual reflectors are now called “superscatterers”.

Superscatterers are the puffer fish of electromagnetics: they have a radar signature or “radar cross section” (RCS) that is bigger than they really are. This RCS increase can be dramatic, in excess of 15 dB, with the fractal solutions.

Furthermore, the RCS increase can be tailored at multiple channels or bands with fractals, allowing the radar to interpret the brightened fractal superscatterers with a spectral signature, acting as an identifying “fractal license plate” on each, if desired.

Per Fractal, superscatterers solve the big problem of driverless cars, because they can be tiny while bright to car radar. They can be installed in the roads, on signs, on barriers, and other vehicles. The proprietary invention also extends to including the fractal superscatterers into road reflectors (visible light), extending the utility of a safety device already employed, and making it dual use.

Car-based radar can be dramatically more effective with the radar-bright fractal superscatterers. In contrast, LIDAR based systems, with their “car beanie” laser systems, no longer have an advantage over radar, and will eventually be antiquated. The expense, and detrimental appearance of car LIDAR will disappear on future driverless cars and roads.
