摘要
Abstract
To satisfy the conditions for calculating the parameters cited war and kill probability, the warhead muzzle velocity and its distributions were studied. According to external ballistics and aerodynamics,the variation conditions of velocity and acceleration of dynamic-burst fragment were studied by analyzing the force and motion of dynamic-burst fragment. Aiming at the non-stationary process, the high-resolution short-time Fourier-analysis-method of adaptive window-length was proposed by applying the motion equation of dynamic-burst fragment. This method can improve the velocity-measurement precision of dynamic-burst fragment,and it is more suitable for dynamic measurement.关键词
