Methods and application of comprehensive situation analysis for rocket debris landing points
With high-density space launch mission,the number of rocket debris shows a rapid growth-trend.The comprehensive situation of rocket debris landing points is the most important basis for assessment of rocket debris risk and emergence command decision-making.Fristly,the business requirements model and topic domain data model are proposed.Then,some relative data mining analysis methods are studied which based on the data resource of rocket debris landing points,such as the accuracy analy-sis of rocket debris landing points prediction,the accuracy analysis of preplan-region for rocket debris and the scattering area fea-tures analysis of the landing points.Last,visual design elements of situation map for rocket debris landing points in space launch mission are discussed.Engineering practice has shown that this research has application value and can be the technical support for risk assessment of rocket debris and emergence command decision-making in space launch mission.
