Abstract: This paper investigates electromagnetic wave propagation and regulation in spatial environments,and discusses target recognition principles and characteristics of automotive sensors in driving assistance. Focusing on millimeter-wave radar installation and calibration in vehicle manufacturing,a specialized electromagnetic wave environment survey technique is proposed. This method simulates electromagnetic wave environment in actual calibration by replicating radar installation configurations on completed vehicles. The evaluation methods and improvement measures for the current environment are introduced.

Key words: automotive industry, radar calibration, electromagnetic wave environment, millimeter-wave radar, driving assistance
