SS3060 / SS4090
Dual Frequency Side Scan SonarSS3060 and SS4090 (Seagull) is a dual-band broadband high-definition side-scan sonar designed for general survey requirement. The system adopts a number of innovative technologies including broadband signal processing, variable aperture, image equalization, 4K HD display technology to fulfill customer requirements on wide scanning range and high definition. The system is widely applied in shallow water operations such as underwater engineering inspection, pipeline investigation, fire emergency search and rescue, underwater archaeological survey, marine pasture investigation and environmental protection hidden pipe inspection etc.
Features
- High Resolution: With 60kHz bandwidth signal, SS3060 and SS4090 adopt pulse compression or ultra short pulse transmission to improve the ranging resolution in the across track direction from the system level and enhance scanning image resolution too.
- Clear Image Near or Far: It adopts variable aperture dynamic focusing technology to increase scanning image’s depth of field and effectively resolve near field blur problem of general side scan sonars, SS3060 and SS4090 can get clear and consistent image from both far and close range.
- Delicate Image: Innovative image equalization technology combines software of real-time contract adjusting and hardware of 24bits high dynamic AD to enhance the image contrast and definition. This is the reason that SS3060 and SS4090 can present the terrain background image so delicately.
- Diversified Applications: Cable and pipeline survey, hydrological survey, archaeological survey, ocean energy and mining resources detection, environmental protection investigation and port safety, etc.
