Determination of Precise Instantaneous Height at Multibeam Transducer

克服缺点传统多微笑调查并且数据处理，一个新方法为即时高度的精确决心被介绍在多，由 GPS 高度和举的混合的横梁变换器发信号。信号需要被态度修正首先改正到变换器中心的 Beforesignal 混合， GPS 高度和举。第二， GPS 高度需要被举支票和修正本身检查并且修改。黄油价值和快速傅里叶变换(快 Fourier 转变) 在信号混合被使用。最后，快速傅里叶变换被认为在信号处理适当。新方法高效地克服传统的方法的缺点，并且这是由 MBS 的证明的井(多微笑深测术的系统) 实验。

To overcome the shortcomings of the traditional multibeam survey and data processing, a new method is presented for the precise determination of the instantaneous height at the multibeam transducer by the blend of GPS height and heave signals. Before signal blend, GPS height and heave signals need to be corrected first to the transducer center by attitude correction. Second, the GPS height needs to be checked and modified by heave check and modification itself. Butterworth and FFT （fast Fourier transformation） were used in the signal blend. Finally, FFT is thought to be appropriate in signal processing. The new method efficiently overcomes the shortcomings of the traditional method, and this is proven well by the MBS （multibeam bathymetric system） experiment.
