Electromagnetic Characterization of sUAVs Through Polarimetric Radar Cross-Section Analysis

Based on a linear error model and state-of-the-art calibration techniques, high-resolution polarimetric radar cross-section (RCS) measurements of small unmanned aerial vehicles (sUAVs) are presented. The RCS is analyzed in the resonant region. The results are discussed in context of dominant coupling paths and radar-based identification of sUAVs.
