摘要
多站无源定位中,测向交叉定位法是一种广泛应用的经典方法,但如何从多个低成本低精度测向传感器获得高精度定位效果的研究相对较少。目标位置信息场定位法在处理多目标定位问题时能够同时确定目标数目和多目标位置,对传感器测量数据具有较好的融合性能。运用目标位置信息场定位法,研究在感兴趣定位区域内用多数低精度测向传感器代替少数高精度测向传感器进行定位,并借助定位算法的GDOP对定位效果进行描述。理论分析与仿真实验表明,目标位置信息场定位法可以用于多数低精度测向传感器测向交叉定位,并且可以达到少数高精度测向传感器同样的定位效果,具有重要的应用价值。
In multi-sensor passive location,Direction-Finding （DF） location is a classic widely used method. However,how to obtain high accuracy of location using a number of low-cost and low-accuracy DF sensors is relatively few researched. The position information field location method can obtain target number and multi-objective position at the same time and have better convergence performance of sensor measurements when dealing with the problem of multi-target location. This paper focuses on using a number of low-accuracy DF sensors to replace a few expensive high-accuracy DF sensors throughout an area of interest by position information field location method. The locating effect is described by Geometrical Dilution Of Precision （GDOP） of localization algorithm. Theoretical analysis and simulation results show that the position information field location method can be practically used to replace a few expensive high-accuracy DF sensors by a number of low-accuracy DF sensors and obtain same locating effect.
