基于令牌和测距的网络化弹药定位方法

针对网络化弹药节点组网自定位的需求，提出了基于令牌的信道接入方法，该方法采用令牌传递控制网络化弹药节点的信道接入，可以解决网络化弹药所关注的信道利用率低的问题，且各节点间不需要时钟同步，有效地提高了组网速度. 提出采用双边对等的信号传播时延测距方法为原理的网络化弹药自定位方法，该测距方法原理简单且同样不需要时钟同步，并消除了内部时间基准漂移对测距造成的影响，较高的测距精度保证了节点的自定位精度. 实验结果表明，此方法可有效地提高网络化弹药的组网速度，相对定位精度满足网络化弹药定位需求. 

A Localization Method of Networked Munitions Based on Token Ring and Ranging

In response to the need of networking and location of networked munitions, a relative localization method was proposed based on token ring protocol and symmetrical double sides two way ranging. The method was an effective solution for the issues of low channel utilize rate and high energy consume concerned in the networked munitions area, and all nodes don't need time synchronization. The principle of symmetrical double sides two way ranging is simple and the location is more accurate eliminating the effect of inner time datum drift. Experimental results show that this method is effective to improve the networking time and the location accuracy of networked munitions.
