Abstract
In order to study the influence of typical vehicle-mounted antennas on human health,the 77 GHz anti-collision radar antenna model,human body model and electric vehicle model are constructed in COMSOL Multiphysics software with 77 GHz anti-collision radar antenna as electromagnetic radiation source.The distribution of Specific Absorption Rate(SAR)of pedestrians at different angles outside the vehicle under the radiation of 77 GHz anti-collision radar antenna is obtained by simulation analysis.The dosimetric assessment of human electromagnetic exposure levels is performed using the full-body average SAR specified in the International Commission on Non-Ionising Radiation Protection(ICNIRP).The simulation results show that when the input power of the antenna is 23.5 dBm,the average SAR of the full-body of the side-standing pedestrian and the front-standing pedestrian is 2.80×10-13 W/kg and 4.95×10-13 W/kg,respectively.Both are far below the basic limit of 0.08 W/kg recommended in the ICNIRP standard,indicating that the electromagnetic exposure level generated by the 77 GHz anti-collision radar antenna will not pose a threat to human health.关键词
