基于无线传感器网络的炮弹落点定位技术的研究

Research of Projectile Impact Point Positioning Skill Based on Wireless Sensor Network

针对现有的炮弹落点定位的缺点,提出了一种基于无线传感器网络对炮弹落点进行实时监控的系统。首先,采用到达时间差对传感器节点进行自定位,然后在传感器节点中集成加速度传感器,利用炮弹撞击地面产生的地震波对炮弹落点进行定位。在此基础上,对系统的软件进行了设计,从而实现了对炮弹落点的定位。对系统的测试结果表明,随着振动信号的减弱,接收到的信号幅值明显减小,利用此方法可以对炮弹落点进行初步的定位。

In order to solve the disadvantage of projectile impact point positioning already have,a system positioning projectile impact point based on wireless sensor network is designed. First of all,sensor nodes were location themselves by TDOA. Acceleration sensor was integrated in sensor node. Projectile impact point localization by using seismic waves impact on the ground. On the basis of this,the software flow of the system is described so that the impact point location can be achieved. The test result show that with the signal of libration bate the amplitude received reduced apparently. Projectile impact point localization can be fulfilled.
