提出一种新的统计方案,以目标面积比为核心度量指标,并参照连续圆形目标定义目标面积比意义上的等效半径,实现对目标宏观尺度大小的量化估计。此方法能有效减轻轨道截断效应所造成的目标尺度低估,可对通过计数类方法得到的目标空间尺度做出有效修正。 更多还原

【Abstract】 A new scheme was proposed in this study to account for such a handicap,which is based on the statistics of object area fraction that is somewhat insensitive to the orbit truncation.In order to get a measurement that could be accurately received,continuous circle object was consulted.Accordingly the equivalent radius was finally defined by using a minimum deviation principle to indicate the object scale.Since the equivalent radius is an indirect indicator of object spatial scale,it could be used ... 更多还原
