摘要现代战争中，科技的进步促使武器弹药向智能化、精确化的方向发展，且要求弹药降低对非军事目标的附带毁伤，同时各国都希望最大限度的节省军费开支，所以提高常规弹药的打击精度成为各国武器研制的焦点问题。弹道修正弹应运而生。本文即针对某型弹药，设计其一维弹道修正机构的弹载计算机。60243

论文首先搜集弹道修正弹的相关资料，对国内外此技术的现状进行归纳分析，从而了解相关软件、硬件设计要求和特点。然后使用Altium Designer软件设计升压起爆电路、铁电存储器电路，并制作PCB印刷电路板；同时使用C语言对选用的ATmega 128单片机进行编程，以接收GPS信号并加以存储。本文的研究为一维弹道修正弹的弹载计算机研制提供了理论依据。

Title  The design and implementation of control circuit of

        one-dimensional trajectory correction projectile 

Abstract In modern war, the progress of science and technology  promote weapons and ammunition to the direction of intelligence,accuracy,and require ammunition reduce collateral damage to non-military targets,at the same time,all countries want to save military spending as far as possible,so improving the hit precision of the conventional ammunition becomes a focal point of weapons development.Trajectory correction appears .This paper aims at a certain type of ammunition,designing the one-dimensional trajectory correction institution of onboard computer.

      Firstly，this paper collects related information,then  sums up and analyses the present situation of the technology at home and abroad ,to understand the design requirements and features of related software and hardware .Then the paper uses Altium Designer software to design booster and detonate circuit,FRAM circuit,and produce PCB printed circuit board; At the same time,using C language to choose ATmega 128 singlechip  programming, in order to receive GPS signals and to store them.The research of this paper provides a theoretical basis for the one-dimensional trajectory correction shell onboard computer development.

Keywords   trajectory correction，boost and detonate，FRAM,singlechip，GPS
