| 摘 要： | 舰船水压场以其难于人工模拟性,被作为舰船的重要目标特性广泛应用于水中目标检测中,而对其进行频域检测又是最常用的舰船水压场信号检测方法。复杂多变的海洋环境中,诸多因素都对舰船水压场信号的频域检测性能产生显著影响,文章对在我国沿海不同海域获得的大量环境水压场数据进行分析,得到影响舰船水压场信号频域检测的主要因素,为水中目标探测器设计提供参考。

| Abstract: | It is widely used in the detector to detect the target as a main ship physical field,owing to ship hydraulic pressure signal is hardly simulated.The general way of the ship hydraulic pressure signal detection is frequency detection.But lots of factors on complicated oceanic state disturb the signal detection in frequency region.This thesis analysed the frequency of the ocean wave hydraulic pressure data acquired at China inshore.And get the main factors of the detection of ship hydraulic pressure signal in frequency region.The conclusions in this thesis provide information for the design of the subaqueous ship detector. |
