| 摘 要： | 为了有效地从风浪背景下检测舰船水压场信号,鉴于舰船水压场信号与海浪水压信号在频谱上的差异,采用求卓越频率下的功率谱的方法对信号进行检测,取窗宽20s,每次计算21个采样点,分别求取海浪水压场的仿真信号及不同波浪级别下海上某目标的水压场实测数据的功率谱进行信号检测,验证了方法的有效性。

| Abstract: | To effectively detect the ship hydrodynamic pressure signal from wind wave background, according to the characteristic difference between the ship hydrodynamic pressure and the wave hydrodynamic pressure on the spectrum, a method of hydraulic pressure signal detection is used on salience spectrum in the paper, select the window width of 20 seconds, calculate each of 21sampling points. Then, the spectrum of some ship hydrodynamic pressure signal is detected based on the dates between emulation and experimentation in the wave hydrodynamic pressure, the method is verified in effect. |
