【Abstract】 Using the principles of state reconstructed and the identification method of multi objective optimization, as to the whole measured data of the trajectory coordinates of LAPB as information source, makes the calculating trajectory (velocityand coordinates) close in upon the measured (or quasi measured) trajectory variables, identifies the key parameters (drag coefficient, full time of main parachute, rejecting velocity and added mass) influencing the trajectory of LAPB. Through the verification of the bombing measured data, demonstrates that the method of dynamics modeling is identical and effective.更多还原
