Abstract:
In order to improve the accuracy of exterior ballistic calculation,the meteorological data interpolation method(MDIM)and modified approximate meteorological layers weight method(MAMLWM)are proposed by analysis of approximate meteorological layers weight method(AMLWM).Based on ballistic meteorological data measured by weather radar,the deviation variation characteristics between actual meteorological data and standard meteorological data such as atmospheric pressure,virtual temperature and atmospheric density are analyzed,and exterior ballistic calculation are completed by using three methods.The results show that the MDIM can truly reflect the influence of actual meteorological data deflection on the fight projectile;and the plus-minus meteorological data deflection is not counteracted by the MAMLWM,and the range computation accuracy can be increased by 60% than AMLWM.
