Laser And Millimeter-Wave Backscatter Of Transmission Cables

Radar cross sections (RCS) of power line cables were calculated and measured at four mm-wave frequencies (18, 34, 56, and 94 GHz) and two laser wavelengths (10.6 and 1.06 pm) as a function of aspect angle. Three polarizations were considered: horizontal (HH), vertical (VV), and cross polarization (HV). Dry and wet cable conditions were simulated, and differing roughnesses were considered. The calculated and measured results are presented in this paper.
