Based on signal detection theory, the real-time leakage detection problem of submarine pipeline was discussed, by means of the observed series of mass flow difference of pipe.
针对海底管道泄漏监测问题,基于信号检测原理分析了受噪声干扰的流量差观测序列。

Then the pipe system becomes the main noise resource of quite submarine, when propeller noise, hydrodynamic noise and machinery noise of facility base are controlled effectively.
