高海况条件下海浪水压场测量实验研究

Measurement experiment study on ocean wave pressure field under rough sea conditions

水雷水压引信具有极好的抗扫能力,但海洋环境复杂,海浪水压场对水压引信造成严重干扰。为获取不同海域、各种海况下的海浪水压场数据,提出了高海况条件下的海浪水压场测量实验方案和实现方法。解决了水下测量系统的低噪声、低功耗、大容量存储等关键技术;克服了恶劣海况下测量体的布放回收、测量体晃动、抗泥沙掩埋等难题。海上试验结果证明了系统的有效性,并在东海成功获取了在台风"桑美"外围影响下的海浪水压场数据。对不同海况下的水压场信号进行了分析,得出了重要结论。

Mine pressure fuze has good ability of anti-sweeping; ocean wave hydraulic pressure field is the primary noise source under complicated sea conditions. An experimental design and realization method is put forward for measuring ocean wave pressure field under high sea conditions. Key techniques for low noise, low power and mass storage issues in underwater test system were solved. Difficult problems, such as placement and refloatation, shake and anti-burial of the measured object and etc. were conquered. On-sea experiment results prove the effectness of the system. A lot of data a- bout ocean wave pressure field under peripheral influence of typhoon Sangmei in East China Sea were obtained and the signal power spectra under different sea conditions were analyzed, which educes several important conclusions.
