微型飞行器电磁导引头定位方法分析及验证

Localization algorithm analysis and test for Micro Aerial Vehicle radio-localizer

对微型飞行器电磁导引头的定位方法进行研究,设计了适合于在微型飞行器平台上使用的电磁导引头原理样机。详细介绍了电磁导引头的定位原理;根据信号的自由空间传播模型,建立了定位测量方程,推导了定位方法;利用仿真的方法分析了测站数、测量误差等对定位结果的影响;介绍了开发的原理样机结构并给出了标定和实验结果。

A micro radio localizer that can be used in micro systems such as Micro Aerial Vehicle （MAV） is proposed.localization principle is discussed in detail.Under the assumption that the electromagnetic wave obeys the free-space spreading model,the measuring equations are established.The determination of several factors of the localization error such as the number of measuring positions and measurement errors is discussed.A radio-loealizer prototype is developed and experiment results are shown as well.
