高分辨图象声纳目标模拟器的设计

The Object Simulator Design of High Resolution Image Sonar

高分辨图象声纳在小目标的探测和识别中扮演重要角色 ,目标模拟器是图象声纳设备调试的主要仪器之一。文章讨论了模拟器信号发生的机理 ,分析了近场和远场声基阵输出的信号模型。

High resolution image sonar plays an important role in detecting and c lassifying the small object in under water. Object simulator is the primary devi ce in measuring image sonar. The principle that the signal generates is discusse d. The acoustic element array output signal model is analyzed for far field and near field. The beam pattern of image sonar is obtained by the simulator.
