A Classification and Identification Algorithm of Interference Sources Based on isodata

Abstract

The present invention relates to an interference source classification and identification algorithm and device based on ISODATA, which belongs to the field of electronic information, and performs classification and identification for unknown interference sources in space: use interference source monitoring and positioning equipment to obtain the PDW of each signal in the area, and the interference source One-dimensional ISODATA calculation is performed for each type of characteristic value output by monitoring and positioning equipment, and the original characteristic value for a period of time is taken out from the characteristic value database according to the queue to be retrieved, and cluster analysis is performed on it by multi-dimensional ISODATA, and the clustering is output to the user in real time The number and characteristic clustering center value are used as the effective characteristics of the most likely interference signal; the quasi-real-time unsupervised cluster analysis is performed on the original monitoring results of the interference source monitoring and positioning equipment, so that the characteristic parameters of the key signals in the monitoring results Clearly presented to users, more flexible and more reasonable.

Description

technical field [0001] The invention relates to an ISODATA-based classification and identification algorithm for interference sources, which belongs to the field of electronic information. Background technique [0002] With the rapid development and wide application of information technology, electromagnetic space has been included in the category of national interests. The complex electromagnetic environment is an important feature of the information age. The radiation power of radar detection, communication, navigation and identification and other electronic equipment in the electronic information system is increasing, the frequency spectrum is becoming wider and wider, the number of equipment has doubled, and the operating frequency is serious. The overlapping makes the surrounding electromagnetic environment more and more complex, making the electromagnetic environment in a limited space very harsh. In view of this, the industrial market has an urgent demand for electro...
