Abstract


Near Spacecraft can pass over the enemy’s airspace quickly, and avoid been found by air defense monitoring system, has broad application prospects and the military value, many countries has began the research on near spacecraft technology. So it’s important to have the research on the interception missile for the near spacecraft, it’s necessary to have a simulation research on the ballistic characteristics about the near spacecraft and the interception missile.This paper has showed some latest developments and research direction about the near spacecraft and the interception missile. Choose the typical near spacecraft White Poplar-M missile as the research object to research. Based on some appropriate simplify and hypothesis, build the math model about the target missile and the interception missile. Consider the maneuver flight of the target, showed the maneuver trajectory generation methods when the target make the sinusoidal maneuver and spiral maneuver. Analyze the ballistic characteristics of the target missile by building math model, make the simulation research on the without maneuver, the sinusoidal maneuver and the spiral maneuver target missile separately. Build the target trajectory tracking filter model with the Extend Kalman Filter (EKF) theory, observe the target tracking error with simulation. Intercept on the target missile with high parabolic ballistic trajectory, calculate the virtual target velocity, the virtual target initial position and the forecast target points, showed a middle guidance method based on the virtual target, gave a high parabolic ballistic trajectory to meet the actual needs. Based on these study, with the guidance method based on the virtual target, simulation research on the intercept to the target without maneuver, sinusoidal maneuver and spiral maneuver separately, analyze the ballistic characteristics about the interception missile
