Abstract

Rainfall can reduce the radar signal through a radome. The effects of different water layers on the radome transmission are studied using quasi-optical measurement from 26 to 330 GHz including water permittivity characterization. The water is deposited as drops of different sizes or as a uniform layer while keeping a constant volume, highlighting the importance of the control of the total wet surface for radar applications. A compact model is proposed to predict the signal loss due to water on the radome depending on the rain flow.

毫米波和亚毫米波通过被水覆盖的雷达罩的传输：水的形状的影响

降雨会降低通过雷达罩的雷达信号。我们利用 26 至 330 千兆赫的准光学测量（包括水介电常数表征）研究了不同水层对雷达罩传输的影响。在保持体积恒定的情况下，水以不同大小的水滴或均匀水层的形式沉积，突出了雷达应用中控制总湿表面的重要性。提出了一个紧凑的模型，用于预测雷达罩上的水根据雨流情况造成的信号损失。

期刊介绍： The Journal of Infrared, Millimeter, and Terahertz Waves offers a peer-reviewed platform for the rapid dissemination of original, high-quality research in the frequency window from 30 GHz to 30 THz. The topics covered include: sources, detectors, and other devices; systems, spectroscopy, sensing, interaction between electromagnetic waves and matter, applications, metrology, and communications. Purely numerical work, especially with commercial software packages, will be published only in very exceptional cases. The same applies to manuscripts describing only algorithms (e.g. pattern recognition algorithms). Manuscripts submitted to the Journal should discuss a significant advancement to the field of infrared, millimeter, and terahertz waves.
