Acoustic positioning system has wide application in ocean scientific field. however, existing systems have disadvantages of bulkiness, perplexing operation, limited position range and low precision, resulting in their incompetence of satisfying many application needs
水聲定位系統在海洋科學領域應用廣泛，但原有系統大多或設備龐大、操作復雜，或定位范圍小、精度低，很難真正下滿足使用需求。 -
Range ambiguities and phase wrapping are the two main problems during acoustic ranging, direction finding, tracking and positioning. we mainly discuss range ambiguities
距離模糊和相位模糊是水聲測距、測向、跟蹤定位中的兩大模糊問題，抗距離模糊是本文研究的主要內容。 -
Acoustic positioning system
音響測位裝置 -
Active underwater acoustic positioning / tracking systems locate target by measuring the range from object to receiving sensors. usually the target - receiver range can be got by the propagating time of a signal pulse. if this propagating time is larger than the pulse repetition period, it will mean that more than one signal pulse are on propagation
主動水聲跟蹤定位系統通過測量脈沖信號的傳播時延可以測得目標相對接收機的距離，當此傳播時延大於系統同步周期時，時延測量就會呈現不確定性，可能相差若干個重復周期，導致定位解多值，稱之距離模糊現象。
