An analysis of issue related to rain attenuation for radar signals

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 minimal. The attenuation by rainfall is at least 0.06dB in the L band and 20.2dB in the X band. Finally, the attenuation by atmospheric factors is at least 0.416dB in the L band and 22.8dB 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.
