A recognition algorithm for high voltage transmission lines at horizontal polarization millimeter-wave radar

In this paper, the radar phenomenology of high voltage transmission line (HVTL) is studied for examining the feasibility of recognizing HVTL using the horizontal polarization millimeter-wave radar system. For this purpose, horizontal polarization RCS and high resolution range profile (HRRP) of some HVTL are calculated at 34 GHz. Based on the observed behavior, a horizontal polarization recognition algorithm that makes use of the scattering feature caused by the braided structure of HVTL is proposed. The performance of the algorithm is demonstrated experimentally.
