中文摘要：
在分析最近邻方法理论的基础上，提出了一种新的雷达辐射源信号识别结构，引入了一种新的距离贴近度度量方式。建立了基于最近邻方法的雷达辐射源信号识别模型，并分别在大样本和小样本数据集合对不同噪声背景下的雷达辐射源正确识别率和识别时间进行了比较分析。仿真表明，基于最近邻的雷达辐射源信号识别方法简单易行，快速简洁，有较高的正确识别率。
英文摘要：
A new radar emitter signal recognition model is put forward based on analyzing k nearest neighborhood method, and a new distance close degree measurement is introduced. The radar emitter signal recognition model based on k nearest neighborhood method is designed, then performances of right recognition rate and recognition time are compared in different noise background. Simulations show that the recognition method based on k nearest neighborhood is simple to carry out and higher recognition rate can gain.
