NARROW BEAM
数字成像声纳
DIGITAL IMAGING SONAR
串行通信
(Serial Communications）
采用串口通信一体机，高性能数字成像声纳可以在1米范围内的一个2毫米距离分辨率内每秒拍摄超过35次，产生近摄图像质量。
881A可以定制配置或恢复到默认设置以匹配合适的操作范围尺度。
Using Serial communications, this all-in-one, high performance digital imaging sonar can exceed 35 shots per second on the 1 m range at a 2 mm range resolution, producing near-photographic image quality.
The 881A can operate with customized configurations or revert to default settings to match appropriate operating range scales.
The 881A can operate with customized configurations or revert to default settings to match appropriate operating range scales.
