The two processes of the terminal sensing ammunition (TSA) system in the air arethe opening of the parachute and the stable scanning of the system. The latter is veryimportant in actual battles. In this paper, we have mainly studied the calculating of theparachute during the course of its opening and the creating of two-body motion'sdynamic model including its programming computation. Some parameters of theparachute's designing come from the calculating of the parachute during the course of itsopening, also we can get the system's path during this non-stable state stage. Using theknowledge of the dynamics to analyze the force and the moment on the system aftersimplifying the terminal sensing ammunition system as the two-body motion's dynamicmodel. In order to eliminate the wrong points in the program, we use four elements lawto modify the system's equations getting from the two-body motion's dynamic model,then we obtain the final system of equations which is used in the program. Union theexample, programming calculates with VC++ using the geometrical and kinematicsrelations among different parts of the system. Drawing some scanning picturesaccording to the results of the program including the falling velocity, the rotation speed,the scanning angle and the scanning space.At last some influences which cause the change of the system's scanning are alsoanalyzed in this foundation. The system considering the ballistic wind is discussed, morerealistic pictures of scanning are presented.
