摘要

精确位置估计的一个关键因素是检测和分配测量误差的能力。这些误差可能是由电磁波传播路径内的干扰以及硬件本身引起的。本文详细讨论了到达时间差(TDOA)局部位置估计系统的误差估计。提出了估计路径相关错误和硬件相关错误的场景。所开发的基于卡尔曼滤波技术的算法得到了实测验证。

Error estimation for reliable fault detection of a TDOA local positioning system

A key element in precise position estimation is the ability to detect as well as to assign measurement errors. These errors may be caused by disturbances within the propagation path of the electromagnetic wave as well as by the hardware itself. In this contribution the error estimation for a time difference of arrival (TDOA) local position estimation system is discussed in detail. Scenarios are proposed to estimate path-related errors, as well as hardware-related errors. The developed algorithms, which are based on Kalman filtering techniques, are verified with measurements.
