Study of transmission effects of millimeter wave through fog and haze
With the decline in air quality, China has frequently appeared foggy and hazy weather. It would have a negligible impact on the detection performance of millimeter wave systems. In this paper, the physical characteristics of fog and haze are discussed in detail. The mechanism of millimeter wave attenuation through fog and haze will be introduced as well. Calculation model of fog scattering and atmospheric absorption attenuation during millimeter wave propagation are established in this paper. Based on the above analysis, it works out the total attenuation consists of the haze scattering and atmospheric absorption, and further analysis the performance of the millimeter-wave systems working at non-atmospheric windows emphatically. The result shows that it has superior anti-reconnaissance performance and anti-jamming performance at non-atmospheric windows.
