Abstract: Rollingvaneelectrostatic detectors were arrayed as a square to obtain information about the aerial target. According to the structure of the rollingvaneelectrostatic detectors and the theory of electrostatic induction, the location algorithm for aerial target was derived. The orientation software and interface were compiled, based on the location algorithm. The location software can show the position of the aerial target in real time. The location algorithm proves to be feasible. 
