| 中文摘要: |
| 本文基于波浪观测谱的反变换，即采用线性迭加（傅利叶重构）法及解卷积滤波法实现波浪仿真，在此基础上，进一步确定波浪脉冲回声到达时间和波浪声散射强度（平均回声级）及起伏规律，并由８０９８单片机硬件实现。 |
| 英文摘要: |
| Based on the inversion of measured wave spectrum, this paper presents a method of simulation of wave fluctuation by using the Fourier Reconstruction and De- convolution filter. Furthermore, the paper finds the arriving time and backscattering density of the echo and discribes the simulation hardware using 8098 microcontroller. The results may serve as reference to underwater active detection. |
