港灣防衛一直是各個國家非常重視的議題以及發展的方向,在本論文中將自行整合一套水下聽音陣列系統用於在高雄港灣偵測水下目標物。包括
1. 硬體的整合(類比轉數位記錄器、4顆水下麥克風、電力供應配線)
2. 訊號之設計(線性調頻訊號)
3. 電源的配置(鋰電池*4)
4. 訊號處理技術
完成高雄港灣主動偵測聲納系統。
本研究為測試此水下聽音陣列系統的正確性於2017年5、6月時以海研三號研究船(R / V OCEAN RESEARCHER III)進行量測實驗,測試地點小琉球附近海域,共包含了2次的航次測試,針對本系統進行校正實驗,以對本系統之正確性進行測試。完成系統測試後在同年12月時會回到高雄港內分別進行了被動以及主動的聲學實驗,在被動實驗中先了解港灣內不同目標物的聲紋特徵以及高雄港灣噪音的頻段。在主動實驗中使用定點自收發進行聲學實驗,在對於水下目標物進行訊號的拍發,透過水下聽音陣列接收回波來對其做偵測。
實驗結果顯示本研究所整合之水下聽音陣列系統,可以透過主動聲納方式對於水下目標物進行偵測,並發現在港灣此種極淺海域(實驗水域3~4公尺)時訊號打到目標物時會因為邊界效應導致系統無法接收到目標物回波,故在本論文中會討論在港灣環境中接收不到目標物回波時的可解決辦法,並利用此辦法在應用高雄港海域中,期盼日後可應用於港灣防衛系統發展。
Harbor defense has always been a topic of great concern to many countries and the direction of development. In this paper, an underwater listening array system will be integrated to detect underwater targets in Kaohsiung Harbor. Include:
1. Hardware integration (analog to digital recorder, 4 underwater microphones, power supply wiring)
2. Signal design (linear frequency modulation signal)
3. Power supply configuration (lithium battery *4)
4. Signal processing technology
In order to correctness of array system, the measurement experiment in May and June 2017, and the test site was near Ryukyu. The calibration experiments were performed on the system to test the correctness of the system. After completing the system test, return to Kaohsiung Port for passive and active acoustic experiments. In the passive experiment, understand the voiceprint of different targets in the harbor and the frequency band of Kaohsiung Harbor noise. In the active experiment, the self-transmission and acoustic experiments are performed, and the signals are transmitted to the underwater target, and the echo is received through the array to detect it.
The experimental results show that the underwater listening array system integrated in this study can detect underwater targets through active sonar. When the target is reached, the system will not receive the echo of the target due to the boundary effect. Therefore, in this paper, the solution to the target echo in the harbor environment will be discussed, and the method will be applied to Kaohsiung Port.
