雷达辐射源识别中数据库的构建及应用

摘要

为满足雷达辐射源识别技术发展和特征参数挖掘的需要,在分析辐射源基本信息和特征参数以及二者之间关联关系的基础上,通过数据库管理系统SQL Server,以E-R模型、数据类型设计为切入点,分别构建了雷达辐射源信息库和特征库.最后,分别从雷达辐射源数据可视化管理、信号调制类型识别、辐射源匹配识别等方面探究了数据库的应用实例.从应用实例的运行效果来看,验证了所构建数据库的科学性和可行性.%To meet the requirements of identification technology development and characteristic pa rameter discovery of radar emitter,the basic information and characteristic parameters of emitter as well as their relationship have been analyzed.The information database and characteristic database of the radar emitter have been constructed through the database management system SQL server and with the points of designing E-R model and data type.Application examples on the aspects of the visible management of radar emitter data,the modulating type identification of the pulse signal and the matching identification of the emitter have been studied.Running results of the application examples prove the database constructed scientific and feasible.
