摘要
主要讨论了在二维空间内,利用激光干涉仪对目标进行跟踪滤波时,干涉仪的布局对跟踪精度的影响。通过理论分析得出,跟踪精度主要受目标距离干涉仪的远近以及目标与干涉仪的夹角的大小有关,与所选择的坐标系无关。目标距离干涉仪越近,跟踪精度就越高;目标与干涉仪所形成的夹角越大,跟踪精度越高。最后的仿真结果与理论分析结果相一致。
In this paper, the author discusses the relation between laser interferometers layout and the target tracking accuracy in 2-dimensional space, when laser interferometers are used as sensors to track target. Based on theoretic analyses, a conclusion is drawn that there are only two factors affecting the accuracy: one is the distance between laser interferometers and the target, and the other is the angle between them. The closer the distance or the higher the angle, the higher the accuracy. And the accuracy has no relation with the coordinate system. Finally, a simulation experiment shows the same result as that of theoretic analysis.
