The present invention provides a method for robust estimation of the velocity of a target using a host vehicle. The method for robust estimation of the velocity of a target using a host vehicle equipped with a radar system comprises the steps of: determining a plurality of radar detection points, determining a compensated range rate, and determining an estimation of a first component of the velocity profile equation of the target and an estimation of a second component of the velocity profile equation of the target by using an iteratively reweighted least squares methodology comprising at least one iteration. The estimations and of the first and second components and of the velocity profile equation are not determined from a further iteration of the iteratively reweighted least squares methodology if at least one statistical measure representing the deviation of an estimated dispersion of the estimations and of the first and second components and of a current iteration from a previousiteration and/or the devi
