摘要
针对现有雷达信号特征描述方式很难有效地对复杂雷达辐射源进行描述和识别,提出一种基于脉冲样本图和Vague集的雷达辐射源识别新方法。该方法把雷达辐射源识别问题转换为Vague集的多属性决策问题,不仅能很好地解决雷达信号识别中的模糊问题,而且无需传统方法的特征提取过程,简化了处理环节。另外,基于脉冲样本图的雷达辐射源识别是利用有序的多个脉冲同时匹配识别,因此更可靠。计算机仿真表明该方法是有效可行的,为复杂雷达辐射源识别提供了一种新思路。
The existing feature description of radar signal can not describe or recognize the complicated radar emitter efficiently.In order to solve the problem,a novel method of using Pulse Sequence Pattern（PSP） and the Vague Set is proposed in this paper.The problem of radar emitter recognition is transformed into the problem of multi-property decision of Vague Set.This technique not only can solve the problem of fuzziness in radar signal recognition,but also do not need a process of feature extraction as conventional method,so the process is reduced.In addition,in the PSP-based radar emitter recognition ordered multi-pulses are used for matching synchronously,so the recognition results are more accurate.Computer simulations show that this technique is practicable and effective and offers a new idea for radar emitter recognition.
