摘要: Antenna gain impact on ultra-wideband wind turbine blade deflection sensing is studied in this paper. Simulations are applied with a 4.5-m tip. The antennas high (HG) and low (LG) free space simulated inside blade. It interesting to find that tip HG LG have similar realized when allocated blades, so the emission power for blades can be same. antenna impacts time-domain pulse waveforms distributions around carefully investigated (with blade). Higher enlarges both direct multipath but different levels. To verify simulations, measurements performed full 37-m Pulse delay profiles measured. From all studies, it follows that, effective (or equivalent) isotropic radiated power, an gives stronger amplitudes better accurate reliable distance estimations than LG. Moreover, also closer surface, which important of over 37 m.
