摘要: 利用FEKO产品对高空气象探测雷达场强进行建模,获取相对场强的离散值,研究并比较了双线性内插法、反距离加权法(k=1)和(k=2)、边界平滑的反距离加权法(k=1)和(k=2)5种内插方法计算的高空气象探测雷达在任意方向的相对场强。结果表明:任意方位角和天顶角范围内,双线性内插法计算的高空气象探测雷达场强的拟合度最好;在主瓣区域采用小于等于0.5°,旁瓣区域采用小于等于0.1°间隔的初始场强,仿真结果可以满足高空气象探测雷达模拟训练系统的需求。

Abstract: Based on the FEKO (Feldberechnung bei Korpern mit beliebiger Oberflache) products,the strength of the high-altitude meteorological radar field was simulated.The discrete values of its relative field strength were obtained.Five kinds of interpolation methods,including the bilinear interpolation method,the inverse distance weighted method with k=1 and 2,respectively,and the inverse distance weighted method based on an edge-smoothness with k=1 and 2,respectively,to calculate the relative field strength of high-altitude meteorological radar in any directions were compared.The results show that at any azimuth and zenith angles,the bilinear interpolation method performs the best results.Under the condition that the initial field strength is at intervals equal or less than 0.5 degree in the main lobe and equal or less than 0.1 in the side lobe,its simulation results can meet the needs of the meteorological radar to simulate a training system.
