| Definition | A programmable multi-frequency digital scanning imaging single-beam echosounder. It is used for a variety of applications including surveying, dive support, search and recovery, underwater inspection and archaeology, and scientific research. It can be mounted on small vessels or on ROV, AUV and UUVs. Imaging sonar is primarily used for visual interpretation and uses a fan-shaped acoustic beam to scan a specified area or target. The 881A Imaging has default operating frequencies of 310 kHz, 675 kHz or 1MHz, but other frequencies are tunable from 280 kHz to 1.1 MHz in 5 kHz steps via programmable software configurations. The beam width varies from 2.4 to 1.4 degrees depending on the frequency specified. The aluminium-housed instrument can operate up to 1000 m depth; a titanium-housed version is also available which operates up to 3000 m depth. At a range of 1 m to 4 m, it has a resolution of 2mm. At a range of 5 m or greater, it has a resolution of 10 mm. The minimum detectable range is 150 mm. | ||
