Polarization Sensitivity of Short-Range S-band Radar Sensing System

Wireless sensing based on radar devices is used today in various environments to ensure sustainability and protection of natural resources, to save time and energy in industry and agriculture, and in many other applications. Development of radar technology, in particular in millimeter-wave frequency bands, has opened many new applications which are being currently developed. Important aspect of these systems is increased level of system autonomy based on the principles of machine learning or artificial intelligence. In order to exploit these advantages, we need to acquire as much as possible measured information which can be used later in various detection scenarios. Our aim is to perform a polarization sensitivity analysis for a simple S-band FMCW radar system. The acquired measured results demonstrate the differences when scanning the polarization and give us a indication on how this can be exploited in future systems with polarization diversity.
