    • A method and an arrangement are provided for producing a computed distribution of speeds of scatterers in a target volume (1701). An estimate distribution of speeds at which scatterers would move in said target volume is provided (1201). It is converted (1202) to a candidate autocorrelation function that represent autocorrelation data points that a pulse radar would measure from the current estimate distribution. The fit of a candidate ACF to a measured ACF is measured (1203). The estimate distribution is accepted if a measured fit fulfils a predefined acceptance criterion, or modified (1205) in which case processing returns to the conversion of the modified estimate distribution to an ACF. An accepted estimate distribution is output (1206) as a computed distribution of speeds that describes said actual distribution of speeds.
    • 一种方法,并且提供用于在靶体积(1701)制作的散射体的速度的计算的分布的布置。 在其中散射体将在所述目标卷移动速度的估计值分布提供(1201)。 它被转换(1202)到候选自相关函数确实表示自相关的数据点没有一个脉冲雷达将从目前的估计分布测量。 候选人ACF的测量ACF的拟合测量(1203)。 如果测量的配合满足预定接受标准的估计分布被接受,或在这种情况下修改(1205),处理返回到在ACF改性估计分布的转换。 接受的估计分布是输出(1206),其速度的计算的分布并描述了所述速度实际分布。
