Description

Main Features

High Resolution: With 60kHz bandwidth signal, SS4090 adopt pulse compression or very short pulse transmission to improve the ranging resolution in the vertical track direction from the system level and so improve image resolution.
Dual Frequency working at the same time: 400kHz is for bigger range and 900kHz for high resolution, they would not interfere with each other.
Clear Near or Far: With variable aperture dynamic focusing technology to enhance image field depth and effectivly resolve side scan sonar traditional near field blur problem, SS4090 scanning image is very clear no matter near field or far away.
Delicate image: innovative image equalization technology is adopted to enhance image contrast and present the terrain background image in high-definition.
Diversified Applications: Cable and pipeline survey, hydrological survey, archaeological survey, ocean energy and mining resources survey, environmental protection investigation and port safety, etc
