摘　　要：圆阵干涉仪是一种特殊的二维测向系统,具有解模糊概率高、测向精度高的特点,在电子侦察领域有广阔的研究前景。在实际应用中,存在方位面和俯仰面安装尺寸不同的情况,当圆阵干涉仪直径大于其中一维的安装尺寸,则天线阵面无法安装。针对此类应用场景,考虑压缩圆阵干涉仪的某一维尺寸,将其转变为椭圆阵干涉仪,以满足安装需求。因此建立一种基于k-means聚类的均匀椭圆阵干涉仪测向模型,实现均匀椭圆阵干涉仪的解模糊,并通过仿真分析验证该算法的正确性。The array interferometer has a broad research prospect in the field of electronic recon-naissance due to its special two-dimensional direction finding system,which has the characteris-tics of high probability of fuzzy resolution and high accuracy of direction finding.In practical ap-plication,the installation dimensions of azimuth and pitch planes are different.When the diame-ter of the circular array interferometer is larger than the one dimension of the installation dimen-sion,the antenna array cannot be installed.For this kind of application scenario,a certain dimen-sion of the circular array interferometer is considered to be compressed and transformed into an elliptic array interferometer to meet the installation requirements.Therefore,a direction finding model of uniform elliptic array interferometer is established.This algorithm is based on K-means clustering to realize the de-phase fuzzy of uniform elliptic array interferometer.The correctness of the algorithm is verified by simulations.
