Simulation Study, Based On The Ballistic Missile Radar System Scene

Radar Simulation System is the model established the radar system by the computer software, then it reappears the dynamic work process of the radar system on the computer. in this dissertation, we make a deep research on the trajectory character and attitude character of the radar target in the midcourse. Much work has been done to simulate the trajectory and attitude, we get the attitude parameter of radar target by coordinate transferring.This work can be summarized as follows:1) We define several reference frames, including Earth reference frame, Radar reference frame, Target reference frame. Then, we give the conversion relationships on the basis of introducing the model of the conversion model.2) We analyse the locomotion equation, trajectory parameter, trajectory ellipse parameter , average angel velocity formula under the condition that we only think about the G-force. We ascertain the relationship of the target place and the moving velocity and flying time by Keplei equation, and ascertain the trajectory and the data of the place target landing, finally we analyse the effect on the target trajectory and landing from the earth's rotation itself. and compare different trajectorys and landing places under two conditions , considering about the earth's rotation itself and neglecting it.3) We research the attitude character of the radar target in the midcourse, analyse the rotation of the target in the midcourse on the basis of the attitude dynamics of space target. with the data of the trajectory in the midcourse, we calculate attitude parameter of the ballistic missile.4) We analyse the space meeting and the time meeting between the radar beam and the radar target. Space meeting includes radar beam availability distance, the angel scope that radar can observe, the difference because of the earth's covering. Finally, we analyse the meeting of the target and radar sub-beam.5)According to the requirement of this project, we introduce the arithmetic and itetaror of STL, and analyse the advantage and disadvantage of several data containers in this project. In the end ,we show the flow chart of the multi-targets system.
