Research Of Motion Trail Simulation For Space Flight Targets

This paper is based on a background of a radar equipment space target simulationsystem.The system is a powerful tool for radar system and signal processor to debug.It cansimulate the target movement characteristics and generate echo data.Therefore,radar systemcan debug and test efficiently, shorten the development cycle and cost savings.This paper set up mathematical models for space flight targets,adding jiggle movement.This paper verify the correctness of the model theory.It implement the model through MFCapplication.The major contents are as follows:It analyze the theory of space flight targets movement,including space coordinatesystems and their convertions, Kepler’s three laws;the mechanical environment we shouldconsider,the conceprion and application significance of micro motion; For numericalsolving the initial value problems of ordinary differential equations, this paper introduce theRunge kutta method.This paper set up3mathematical models for space flight targets,including the idealgeometric trajectory model, model of the elliptical orbit without disturbing force,and modelof the elliptical orbit with disturbing force.This paper study posture change rule caused bymicro motion.At last,this paper implement the model.
