中文摘要: 现在的定位算法通常是二维形式的,在基于扩展卡尔曼滤波的TDOA/AOA 算法的基础上推导出了该算法的三维形式。在本文中将方位角、俯仰角、TDOA 三个量构造成符合扩展卡尔曼滤波器的模型,可求得三个分量,从而最终得到移动基站的位置估计。我们仿真了该方法的跟踪轨迹,推算出参数克拉美罗下限

Abstract:For now the positioning algorithm is usually two-dimensional form. Based on the TDOA /AOA algorithm which is on the basis of extended Kalman filter, we derive the three-dimensional form of the algorithm. In this article, three quantities including azimuth, pitch angle, TDOA constructes a model that in line with the extended Kalman filter. Thus the three coordinate components can be obtained, and ultimately get the location of the mobile base station estimates. We simulated the tracking trajectory of the algorithm, and deduced the parameters Cramer-Rao Low Bound (CRLB).
