Abstract:
In this paper, the act ion o f w ind, a ty pical random pro cess, is regarded as an example. Sharping f ilter of RBS is used w ith the actio n of random w ind. It s pr incipal is that the color noise is put out w hen pseudo random numbers of g aussian dist ribut ing f rom the gener ator go by the shaping filter. T he dif ferential equations of shaping filter and ang le mot ion equat ions o f ballist ics are made into the simultaneous equat ions, then the completed simulat ing model of RBS is established. T he spread of rocket is calculated by use of the t radit ional stat ist ical analy sis approach- Monte-Carlo metho d when the techno logy of unfolding f ins is used. T he result of simulatio n pro ved the correctness of the theo ry of shaping f ilter . And the feasibility of the w hite co lor noise and the o pt imal t ime of unfolding fins of this ty pe o f rocket is given.
