ISODATA-based interference source classification and identification algorithm and device

Abstract

The invention relates to an ISODATA-based interference source classification and identification algorithm and an ISODATA-based interference source classification and identification device, which belong to the field of electronic information, and perform classification and identification on unknown interference sources in space. The ISODATA-based interference source classification and identification algorithm comprises the steps of: acquiring PDW of signals in a region by using an interference source monitoring and positioning device, subjecting each class of eigenvalue output by the interference source monitoring and positioning device to one-dimensional ISODATA resolving, extracting an original eigenvalue within a time period from a queue to be retrived in an eigenvalue database, performing clustering analysis on the original eigenvalue by adopting multi-dimensional ISODATA, outputting a number of clustering and a feature clustering center value to a user in real time, and regarding the number of clustering and the feature clustering center value as effective features of a most possible interference signal. The ISODATA-based interference source classification and identification algorithm and the ISODATA-based interference source classification and identification device perform quasi-real-time unsupervised clustering analysis on an original monitoring result of the interferencesource monitoring and positioning device so as to present feature parameters of key signals in the monitoring result to the user, have higher flexibility, and are more reasonable.
