| 摘 要： | 研究MR／GPS制导方案在实行过程中可能遇到的问题。针对制导信号较弱、附加干扰噪声大的特点，运用小波强制滤波的方法，设计了小波滤波器；提出基于MR／GPS系统的弹体滚转测量方案并进行了仿真；对弹道控制的脉冲点火策略进行了研究。仿真结果表明：小波滤波的效果较好、有用信号能量损失小；基于MR的滚转测量方案易于实现，但需进行必要的修正。

| Abstract: | Questions during the implementing of the MR/GPS guiding plan were discussed. To deal with the weakness of guiding signal and the large noise caused by attached interfere signal, a method of filtering obliged with wavelet was used to design a wavelet filter. A measure plan of shell rolling angel based on MR/GPS system was proposed and simulated, and ignition strategy by impulse for ballistic adjusting was analyzed. The results of simulation show that the results of wavelet filtering are better and the energy loss of useful signal is lower. The measure plan of shell rolling angel is easy to practice while the modification is necessary. |
