摘　　要：克里格法在统计意义上是一种对区域化变量的取值求线性最优、无偏内插估计的一种方法。分析了克里格法的插值原理及变异函数的确定方法,利用普通克里格法对海上短波通信可用频率实测数据进行插值,提出了一种新的短波通信可用频率插值方法。通过实测数据仿真验证了该方法的可行性和有效性。对海上短波通信可用频率的选用具有重要的应用价值。Kriging algorithm is a kind of linear optimal and unbiased interpolation estimation method for the values of a regionalized variables in the statistical sense. This paper analyzes the principle of Kriging interpolation and the method for determining variogram. Shortwave communication available frequency at sea measured data are interpolated using Ordinary Kriging algorithm, a new shortwave communication available frequency interpolation method is proposed, and the feasibility and effectiveness of the method by measured data simulation are verified. It is valueable for the shortwave communication a- vailable frequency selection at the sea.
