Abstract: When a new target is detected, if it is determined that the distance difference between the newly detected target and the previously detected target is within a predetermined range, the difference between the relative velocity of the newly detected target and the relative velocity of the previously detected target is obtained to determine whether the difference is greater than a predetermined value nullVa, and when the difference is greater than the predetermined value, it is determined that the new target is a target obtained as a result of mispairing. Further, when the difference between the relative velocity of the newly detected target and the relative velocity of the previously detected target is greater than the predetermined value nullVa,then the difference between a distance derivative of the newly detected target over a prescribe time and the relative velocity of the previously detected target is obtained, and when the difference is greater than a predetermined value nullVb which is smaller than the predetermined value nullVa, it is determined that the new target is a target obtained as a result of mispairing.

Abstract translation: 当检测到新的目标时，如果确定新检测到的目标与先前检测到的目标之间的距离差在预定范围内，则新检测到的目标的相对速度与先前检测到的目标的相对速度之间的差 获得目标以确定差异是否大于预定值DELTAVa，并且当差值大于预定值时，确定新目标是由于错配而获得的目标。 此外，当新检测到的目标的相对速度与先前检测到的目标的相对速度之间的差异大于预定值DELTAVa时，则新的检测到的目标在处方时间的距离导数与相对 获得先前检测到的目标的速度，并且当差值大于小于预定值DELTAVa的预定值DELTAVb时，确定新目标是由于错配而获得的目标。
