摘要 研究采用权重法和最大幅值法改进频谱预报技术,解决了实测加速度数据全频域积分处理中存在的采样时段首尾端因数据长度的有限性和谱泄露积分幅值误差偏大的问题,纠正了积分误差,有效实现了较长时间的波浪预报,为实现基于加速度计阵列的船舶波浪运动检测技术提供保障. By improving the forecasting technique based on frequency spectrum, the integral errors are greatly re- duced at the head and the tail in frequency-domain integral processing of measured acceleration data. The integral errors are maximally corrected, and the wave movements of sealifl ships are suecessful forecasted ahead of time. Measurement of ship wave movements based on accelerometer array is hence practically guaranteed.
