基于C3D辅助的战场传感器监视系统设计与实现

首先介绍了战场传感器监视系统的定义和各国现有典型系统。其次针对战场监视特殊的应用环境,利用C3D辅助技术,将相对定位与基于三维地图环境下的绝对定位相结合,通过坐标转换和地图匹配将位置信息直观准确反映在电子地图上,设计了基于C3D辅助的战场传感器监视系统,并对该系统进行了实现。最后通过对3D-MDS(C,D)定位算法的验证结果表明,在长1000m×7m宽的道路上,布撒120个节点,对于速度为3m/s的装甲车定位误差仅为2.1687米。该系统可对定位算法的定位精度进行评测及误差进行修正,防止由于误差累积造成误差放大。

The Design and Realization of System on Battlefield Surveillance in Wireless Sensor Networks based on C3D Assistance

The definition of System on Battlefield Surveillance and many countries′ typical system in Wireless Sensor Networks are introduced firstly.Secondly,According to the special application about battlefield surveillance and combining the relative localization with absolute localization based on three-dimensional mapping environment,the system based on C3D assistance is proposed and is realized,while using coordinate conversion and map matching to show localization on electron-map.Lastly,the simulation results of 3D-MDS(C,D) localization algorithm show that the position error is 2.1687m,when sensor nodes are placed by randomization and armored car runs at 3m/s on the 1000m×7m road.The system can evaluate position precision,revise position error and avoid cumulate error resulting in error augmentation.
