摘要
为了确定713型双线偏振雷达的探测精度,本文利用电磁波的矩阵传播法计算了考虑椭球形雨滴在不同空间取向下,雨区衰减对713型双线偏振雷达的可测量反射率因子Z_H、差反射率因子Z_(DR)的影响。并利用已有的统计理论讨论了该雷达的取样误差,为实际雷达改装工作提供了依据。
Aimed at determining the measuring accuracy of 713 type dual linear polarization radar, we have discussed the effects of attenuation by raindrops with the shape of spheroid and different orientations on mesaurable parameters such as reflectivity (Z_H)and differential reflectivity (Z_(DR)) by using matrix method for electromagnetic wave propagation. We also have calculated the sampling errors of Z_H and Z_(DR) for the radar by using the statistical theory. This work has provided the base for our remodeling the conventional radar into dual linear polarization one.
