摘要:
针对雷达信号分选中常见的聚类数目难确定、数据簇形状识别、异常数据敏感等问题,提出了基于NeiMu(Neighboring Mutually)的雷达信号聚类分选算法。该算法首先以信号脉冲为点、各点间的欧氏距离为线构建距离矩阵,然后在进行干扰数据剔除的情况下选定合适k值完成聚类矩阵的构建,最后采取遍历聚类矩阵的方法输出聚类结果,在删除无效的聚类后实现了雷达信号的聚类分选。通过仿真可知该算法在选取合适k值的情况下具有极高的正确率,证明了其有效性和可靠性。

Abstract:
For the common problems in radar signal sorting,such as difficult to determine the number of clusters,shape recognition of data clusters,and sensitivity to abnormal data,a clustering sorting algorithm based on Neighboring Mutually(NeiMu) is proposed.Firstly,the distance matrix is constructed by taking the signal pulse as the point and the Euclidean distance between the points as the line.Then,the appropriate k value is selected to complete the construction of the clustering matrix under the condition of eliminating the interference data.Finally,the clustering result is output by traversing the clustering matrix.After eliminating the invalid clustering,the clustering of radar signals is realized.The simulation results show that the algorithm has a very high accuracy rate when the appropriate k value is selected,and prove its effectiveness and reliability.
