| 中文摘要: |
| 从理论上分析了正在跟踪目标的潜艇在其深度变化后,影响声纳继续跟踪该目标的主要因素,从跟踪条件下的声纳方程中,分析深度的变化引起声传播损失和干扰噪声的变化,给出了声传播损失和干扰噪声的计算方法,得出了潜艇变深后保证声纳得以继续跟踪目标的本艇航速及其预报方法和计算实例。 |
| 英文摘要: |
| When a submarine changes its depth, target tracking of its sonar may become unstable due to deterioration of the received signal,to,noise ratio. In this paper, factors affecting the tracking are studied based on the sonar equation and an analysis of the sound transmission loss. The condition under which sonar can keep tracking with change in depth of the host submarine is presented. It is shown that tracking can be preserved by changing the submarine's speed accordingly so that its self,noise is adjusted to satisfy the condition for target detection. |
