The invention discloses a method for analyzing high precision 4D flight trajectory of an
airplane based on real-time
radar data, comprising the following steps: establishing a 4D fight trajectory theoretical model based on the
airplane performance; establishing a 4D fight trajectory empirical model by mining and analyzing based on the historical fight trajectory data of the
airplane types in the above step; combining the theoretical model and the empirical model and quantizing various influencing factors in the
flight process into adjustable parameters; and correcting the 4D flight trajectory mixed models by
radar data to form the final flight trajectory of the airplane. The invention takes the airplane performance into consideration and establishes the theoretical model by performance
library parameters on the basis of a standard flight procedure, thus having high reliability; the invention forms the empirical model by analyzing the historical data, thus having high reality; the invention generates the 4D flight trajectory most similar to the actual flight and can adjust the parameters to form a plan trajectory aiming at the environment of each flight, thus high sensitivity; and the invention correct the plan trajectory by introducing the real-time
radar data, thus having high accuracy.
