摘    要:无线电电磁态势图是依据区域有限采样点形成的整个区域无线电分布的趋势图,是研究区域无线电信息分布的重要方法。利用有限点获取整个区域的分布状态在GIS中主要使用空间插值算法,此法易产生估计误差。在采样点确定的情况下,依据无线电路路测数据空间分布特点,提出了一种将曲面样条插值算法应用于态势图生成的方法,并对算法进行了改进。实验表明:本算法精度比传统算法精度高,证明了算法的有效性,利用本算法可减少测量外业,节约成本提高效率。

关 键 词:无线电态势图  空间插值  曲面插值算法

Abstract:Radio electromagnetic situation map is based on the formation of the regional finite sampling distribution of the regional radio trends,the study area is an important method of distribution of radio information.Finite point for distribution throughout the region is mainly used in the GIS spatial interpolation algorithm,this method is easy to produce estimation errors.In the case of sampling points to determine,according to radio road,spatial distribution of drive test data,a surface spline interpolation algorithm will be applied to situation map generation method,and the algorithm is improved.Experiments show that this algorithm is high precision and accuracy than the traditional method to prove the validity of the algorithm,using this algorithm can reduce the measurement outside the industry,cost savings and improve efficiency.
Keywords:radio situation map  spatial interpolation  surface interpolation
