| 中文摘要: |
| 浅海声传播对空间参数的变化十分敏感,信道冲激响应随空间的变化使水声信号处理的性能受到很大限制。文中采用射线理论模型估计信道冲激响应,用互相关方法仿真计算了信道响应对空间参数的敏感性,并对信道冲激响应空变特性的实际应用进行了讨论。 |
| 英文摘要: |
| Sound propagation in shallow water is sensitive to changes in the spatial parameters like source-receiver deployment.This may greatly influence the performance of underwater acoustic signal algorithm.In this paper,an acoustic ray model is built to compute the channel impulse response,and a correlation method is introduced to analyse by simulation the sensitivity of the impulse response to the spatial parameter.Some application of spatial variability of the impulse response is discussed. |
