摘要:

针对现有雷达信号分选算法依赖人工预设聚类数目且对输入初始值敏感等问题,提出一种基于凸聚类的雷达信号分选算法。凸聚类算法是一种基于目标函数的聚类分析方法,通过优化凸目标函数可以保证雷达信号分选任务的全局最优解,且聚类效果不受雷达信号输入顺序的影响。对截获接收机输出的脉冲描述字进行标准化处理后,构造凸优化目标函数,并使用交替最小化方法(alternating minimization algorithm, AMA)进行优化求解,得到最终的分选结果。仿真实验表明,基于凸聚类的雷达信号分选算法可以获得较高的分选准确率,同时具有较好的稳定性和噪声鲁棒性。

Abstract:

A radar signal sorting algorithm based on convex clustering is proposed to address the issues of existing radar signal sorting algorithms that rely on manually preset number of clusters and are sensitive to initial input values. Convex clustering algorithm is a clustering analysis method based on objective function, which can ensure the global optimal solution of radar signal sorting task by optimizing the convex objective function, and the clustering effect is independent of radar signal input. After standardizing the pulse description word (PDW) output by the interception receiver, construct a convex optimization objective function and solve it using alternating minimization algorithm to obtain the final sorting result. Simulation experiments show that the radar signal sorting algorithm based on convex clustering achieves high sorting accuracy, while maintaining good stability and noise robustness.

Key words: electronic countermeasures, signal sorting, convex clustering, pulse description words, alternating minimization algorithm(AMA) optimization algorithm
