Claim One:
1. A method for producing a computed distribution of speeds of scatterers in a target volume, comprising: a) providing ( 1201 ) an estimate distribution of speeds at which scatterers would move in said target volume, b) converting ( 1202 ) said estimate distribution to a candidate autocorrelation function, hereinafter candidate ACF, that represents autocorrelation data points that a pulse radar would measure by remotely sensing said target volume if the distribution of speeds of scatterers within the target volume would equal said estimate distribution, c) measuring ( 1203 ) the fit of said candidate ACF to a measured ACF that comprises data points that a pulse radar measured by remotely sensing an actual target volume where actual scatterers had an actual distribution of speeds, d) making ( 1206 ) a decision that involves d1) accepting the estimate distribution if the fit measured at c) fulfils a predefined acceptance criterion, or d2) modifying ( 1205 ) the estimate distribution, and repeating steps b) to d) until the decision at step d) involves d1), and e) outputting ( 1206 ) the accepted estimate distribution as a computed distribution of speeds that describes said actual distribution of speeds.
