Radiation from wireless communication devices inside intelligent connected vehicles has been an expeditious growth of concern regarding possible adverse effects on human health. Due to the significant differences in working scenarios compared traditional mobile products, measuring systems specific absorption rate (SAR) are not applicable in-vehicle scenarios. This paper developed a SAR measurement system and method, which suitable for Since hardware methods significantly different systems, it is necessary assess uncertainty new system. influence tissue fluid SAR, this focuses analyzing relationship between SAR. Based validated electromagnetic simulation model, linear quadratic fitting models reflecting properties established. Then, propagation was realized using both Guide Expression Uncertainty Measurement MCM (Monte Carlo Method) through these models. The results analysis were analyzed combination with error. analyses show that error model smaller because there no simple values, thus, more reasonable use method evaluate uncertainty.
