AI Technical Summary
Technical Problem
Radar sensors in motor vehicles experience significant reflection and absorption losses due to radom coverings, leading to false detection, reduced range, and resolution in environmental perception.
Method used
An electro-optical device with non-uniform electrodes arranged in parallel on a substrate, which can be used to reduce transmission losses and enhance radiation transmission through radom coverings, particularly in the gigahertz to terahertz spectrum.
Benefits of technology
The solution significantly reduces transmission losses, allowing for increased radiation transmission without degrading resolution or range, thus enhancing the performance of radar sensors in adverse weather conditions.
