Abstract

Abstract

The wireless channel propagation efficiency is one of the main factors affecting the short range parking system (SRPS) performance. A channel propagation loss coefficient of SRPS is defined for cars, and a propagation loss model based on two-ray model is established. Simulation and measured results show that antenna polarization mode and frequency-influenced path loss is minimum, when tag is along the microwave skylight in car windshield; as tag identification range is less than 10 m, the vertically polarized wave loss is mutated by ground electromagnetic wave reflection. In order to make successful tag identification, the height of the reader antenna should be above 1.18 m.
