椭圆-角度混合定位的GDOP研究

GDOP in Hybrid Ellipse-Angle Positioning Technique

椭圆-角度混合定位是一种基于信号到达时间之和(TSOA)与到达角(AOA)的新型定位技术,又称为TSOA/AOA定位。为了研究定位精度和定位设备布局之间的规律,推导了GDOP的计算公式,并通过仿真分析得到了4条重要结论。

The Hybrid Ellipse-Angle Positioning, also called TSOA/AOA positioning, is a novel wireless location technique, which uses the measurements of Time Summation of Arrival （TSOA） and Angle of Arrival （AOA） tolocate a target. In order to reveal the relationship between precision and the layout of positioning equipment, the GDOP （ Geometric Dilution of Precision） is calculated, and four important conclusions are discovered by simulation.
