本文第一部分简单介绍SGP-1型双侧高分辨力旁视声呐系统。在研制和试用突践的基础上,第二至第六部分对旁视声呐的几个主要问题:旁视声呐方程与最佳工作频率;换能器的动态、近埸指向性;航向分辨力、侧向水平距离分辨力、高度分辨力;航行速度的限制、海底目标的检测与识别;记录声图的变换等进行探讨或分析。并给出有关的计算曲线。提供不同海底地质和非地质目标的记录声图。
The first part of this article briefly introduces the SGP-1 bilateral high resolution paraxial sonar system. On the basis of the research and trial and error, the second to the sixth part of the sonar on the look-aside the main issues: the sonar equation and the optimum operating frequency; transducer dynamic, near-pan directivity; heading resolution , Lateral horizontal distance resolution, high resolution, limitation of navigation speed, detection and recognition of underwater target, transformation of recorded sound image, etc. are discussed or analyzed. And give the relevant calculation curve. Provide sound recordings of different seabed geological and non-geological targets.
