不完备雷达信号信息系统的粒度-粗集处理法

A Algorithm for Incomplete Radar Signal Information System based on Granulation-Rough Set Theory

在粒度和粒度计算的基础上,对不完备信息系统的属性重要度和相对于决策属性的重要度做了定义,并形成了基于粒度方法的不完备信息系统知识约简算法。通过对不完备雷达信息系统实例的分析处理,证明了这种方法的有效性和实用性,并为不完备系统的雷达信号处理提供了一个较好的处理工具。

The significance degree of attribute and that to the decision attribute in incomplete information system are defined on the base of granularity and granularity computing, also a knowledge reduction algorithm for incomplete information system is introduced in this background. A study case of incomplete radar information system demonstrates the validity and practicability of this algorithm, and it supplies a good tool for processing incomplete radar information system.
