Selects the high accuracy low power loss the ultrasonic wave to take the range finder sensor, the constitution ultrasonic sensor network makes the goal the localization and the track. The traditional localization of target follow-up research considers the goal only generally the position, but has neglected the goal size. But the goal size has the vital role in some applications, for instance may help the improvement system's track performance, simultaneously may also take distinguishes and tracks the multi-objective objects the important basis. The ultrasonic wave sensing network tracking system has the precision high, the power loss low merit, but is also facing many limits and the challenge in the actual application, like mutual disturbance, goal between sensor's survey scope limited and so on questions.
