Describes an automated measurement system for mapping the electromagnetic field strength distribution inside and outside vehicles exposed to an electromagnetic field. The system comprises three subsystems: an electromagnetic-field generation unit; a data transmission stage using a magnetic-field probe and a fiber-optic link; and a data control/processing stage consisting of a graphics computer and peripherals. The system is capable of measuring field strength levels between 40 and 85 dBmuA/m with errors within +or-1 dB in a frequency range of 20-200 MHz. Magnetic-field strength measurements of a vehicle exposed to electromagnetic fields inside an anechoic chamber were made using this system. The field strength of the vehicle interior was found to vary with the polarization of an electromagnetic wave, the direction of irradiation, and the body shape of the vehicle.
