Frequency and Polarization Diversity Simulations for Urban UAV Communication and Data Links

Abstract

The purpose of this research was to examine the effects of frequency, and polarization on radio wave propagation in urbanized areas for unmanned aerial vehicle (UAV) data links, and command and control. The transmission from a UAV operating over a small city was simulated using the Urbana Wireless Toolset. Parameters that were varied include frequency, antenna polarization, UAV altitude, and building materials. Multiple reflections and diffractions were included in the simulation. In each case signal contours were generated at discrete frequencies over a 50 MHz bandwidth. It was observed that the signal levels varied up to over the bands at a fixed observation point due to frequency-dependent reflection and diffraction.
