摘要
本文深入研究了二维平面上多传感器的位置对目标跟踪精度的影响。在理论上推导出：用多传感器同时对同一目标进行跟踪时，其跟踪精度主要受传感器和目标所成夹角及目标到各传感器距离的影响。与夹角的关系是：当有两部传感器时，两传感器和目标所成夹角θ_（１２）＝９０°时对目标的跟踪精度最高；当有三部传感器时，传感器和目标所成的夹角分别为θ_（１２）＝θ_（２３）＝６０°时精度最高；与目标到各传感器的距离的关系是：距离越小则精度越高。
This paper deeply studies the influence of multi-sensors' position on the target tracking accuracy on 2- dimensional plane. It is proved in theory that the tracking accuracy is influenced mainly by the included angles and the distance between the target and the sensors when multisensors track the same target. The relation between the tracking accuracy and included angles is: When there are two sensors, the tracking accuracy is the highest if the in- cluded angle θ_(12)= 90°; When there are 3-senders, the tracking accuracy is the highest if the included angles θ_(12)= θ_(23) = 60°. The relation between the tracking accuracy and the distance is: The nearer the distance is, the higher the accuracy is.
