    A kind of effective passive location algorithm,which uses multiple group time delay data obtained in a short period of time,is proposed in this paper. It uses sphere interpolationmethod to calculate the position of the target. Four kinds of formula are given here along with theircomputer simulation results. They have no limitation for the number and position of the sensor ofthe array, and the corresponding calculation is simple. Furthermore, the calculationg time of thebest formula is proportional to the number of the groups of time delay,which is less than othermethod. Finally,this method can also be used to reduce the calculating time of other passive location methods when the array consists of many sensors.
