| 摘 要： | 纯角度目标跟踪问题一般包括二维纯方位跟踪和三维纯角度跟踪两种情形,其特性与所选用的坐标系有关。广泛采用的坐标系是直角坐标系(二维或三维)、极坐标系(二维)和球坐标系(三维)。本文分别在直角坐标系和改进的极坐标系下建立了二维系统模型,并进行了性能分析,指出了后者的优越性。在三维情况下,作了类似工作。最后还以二维问题为例,建立了机动目标跟踪的直角坐标模型和改进的极坐标模型。

| Abstract: | Properties of three-dimensiona;(3-D)bearing-only target tracking sy-stem,and its special case,2-D bearings-only problem,change with respect to coor-dinate system used for system modeling.The widely used coordinate system are Cart-esian coordinate(2-D or 3-D),modified polar(2-D)and modified spherical(3-D)ones.A2-D system is modeled in Cartesian coordinate and modified polar coordinate,respe-ctively,and the results of Performance analysis reveal the superiority of the latter.A Similar work is done for the 3-D problem.A 2-D maneuvering tarcking system isalso modeled as a example in Cartesian and modified polar coordinates,respectively. |
