小范围战术环境下定位系统的设计

无线传感器网络是一种特殊的Ad-floc网络，网络中节点密集，数量巨大且分布在十分广泛的区域。目前，发展前景最为看好的是基于IEEE802．15．4标准的ZigBee无线网络。本文主要介绍基于Zigbee技术的定位系统的设计，结合射频芯片CC2420和单片机芯片PIC18F4620配合实现组成低功耗电路功能模块，并简单介绍了定位的方法。该系统可用于小范围战术环境下的人员定位，适合前线基层连队指挥官对战士方位及战场环境的把握，扩大了指挥与作战半径，增强了部队的战斗力。

The design of a personnel positioning system in a small battlefield

Zigbee low power wireless networks,as the fittest plane for WSN in existing,are paid attention to increasing by people.This paper introduced the design of a personnel positioning system based on Zigbee.We use a radio chip CC2420 and a singlechip microcontroller PIC18F4620 to make a low power circuit module,and briefly introduced the positioning method.The system can be used for small-scale tactical environment of the soldiers position,and for commanders to know the battlefield environment and the soldiers' position.It also expanded the radius of command and combat,and it enhance the combat effectiveness of the units.
