| Abstract: | In this paper,the research progress on domestic and oversea radar base-data Quality Control(QC) technology is reviewed.Three algorithms,the radar echo classifying method based on fuzzy-logic,the QC algorithm based on reflectivity structure and the radar base-data QC algorithm based on neural network are introduced and compared on their design ideology,calculating process and applicability.And the future development of QC technology is also expected.The results show that the QC algorithm based on reflectivity structure can recognize ground clutters efficiently and simply,and it is recommended to be applied in operation. |
