Radiation source information extraction method and system based on pulse description word cluster

The invention discloses a radiation source information extraction method and system based on a pulse description word cluster. The system comprises a pulse description word cluster data preprocessing module, a pulse description word cluster clustering analysis module, a pulse description word cluster time sequence analysis module and a radiation source information feature extraction module. The method comprises the following steps: converting radar pulse analog data acquired by a sensor into discrete pulse data which is called as a pulse description word cluster, and performing data preprocessing according to pulse characteristics to obtain an effective pulse description word cluster; performing clustering analysis on the effective pulse description word clusters to obtain pulse description word clusters of various categories; performing time sequence analysis on the pulse description word clusters of each category, and extracting the pulse description word clusters belonging to the same radiation source; and
