Abstract

In the proposed paper, we analyzed the attenuation by atmospheric factors in the frequency bands for Radar. Radio frequencies using radar systems is susceptible to attenuation by atmospheric factors. The proposed paper analyze the attenuation by atmospheric factors in L, S, C and X bands. Among the attenuation of signals by atmospheric factors, the attenuation by water vapor and oxygen, which is atmospheric attenuation compared to the detection range, is at least 0.416 dB in the L band and 2.6 dB in the X band. The attenuation by rainfall is at least 0.06 dB in the L band and 20.2 dB in the X band. Finally, the attenuation by atmospheric factors is at least 0.416 dB in the L band and 22.8 dB in the X band. In conclusion, it is judged that the attenuation of atmospheric and rainfall is minimal in the L, S, and C bands, and that the influence of attenuation is large in the X band.
