In this paper，on the basis of studying into optimal thrust-direction program，the minimun principle is used to derive approximate analytic solution of the velocity increments of independently targeted warhead. Independently targeting graphs and velocity increment polar plots are proposed to be applied for selecting independently targeting program，including the choicing optimal thrust direction angles，determination of required velocity increment and fuel comsumption together with the selection of optimal sequence of hitting multiple targets chosen and so forth. Computed data are provided for illustration of purpose. Method of analysis used is applicable to arbitrary distributed multiple targets within a certain range of distribution and convenient for primary engineering design and the analysis of the process of independent targeting. The results obtained can be used as a guidance for digital simulation.
