从技术上探求了基于STK平台的相控阵雷达截获IKONOS卫星的方法。简要介绍了IKONOS卫星的基本信息及部分参数，并给出了基于STK的相控阵雷达空间目标监视模型，分析了基于STK的相控阵雷达空间目标监视模型搜索屏的仰角与截获IKONOS卫星次数的关系，为有效监视IKONOS卫星提供了重要依据。

In this paper, the method of phased array radar aquiring IKONOS based on STK is analyzed. The necessary information and some parameters about IKONOS are introduced briefly. A model of phased array radar space surveillance based on STK platform is set up. The relationship between angle of elevation of searching beam of space surveillance phased array radar and the number of captured IKONOS based on STK is analysed, which supplies important basis for IKONOS surveillance.
