摘　　要：根据GPS区域映射系统诱导原理,推导出求解虚拟点邻域的算法,进而在此基础上对映射比例影响的因素进行了分析,主要包括虚拟点位置和转发器分布对映射比例的不同影响,并且对如何在有效干扰区域内通过选择虚拟点的位置和转发器的分布以达到映射比例的优化进行了研究,得到了优化方法,得出的结论可为实际应用提供参考。On the theory of the jamming system through area mapping for GPS navigation,the arithmetic to calculate the neighborhood of illusive point "F" is presented in this paper.Then the influence factors of mapping scale,including the relation between the real point "R" and the illusive point "F" and the distribution of transmitters,have been analyzed.The study conclusion on optimizing mapping scale by choosing two points positions and the distribution of transmitters gives good reference to practice application.
