Abstract

The paper investigates the effect of system geometry of netted sensors on the performance of target position estimation. Each sensor can provide range and bearing measurements, bearing only, or range only measurements. Analyses are based on the Cramer-Rao low bound and geometric dilution of precision in a 2D plane. It is concluded that target position estimation accuracy is dependent not only on the range between the sensors and the target but also on the intersection angles between the sensors' line-of-sight to the target. Scenarios in which there are two or three sensors are discussed in detail.

多传感器系统几何形状对目标位置估计精度的影响

研究了网状传感器系统几何形状对目标位置估计性能的影响。每个传感器都可以提供距离和方位测量，仅提供方位测量，或仅提供距离测量。分析基于二维平面上的Cramer-Rao下限和精度的几何稀释。结果表明，目标位置估计精度不仅与传感器与目标的距离有关，还与传感器与目标的视距交角有关。详细讨论了有两个或三个传感器的场景。
