The ES Series of embedded side scan sonars for USVs and UUVs features frequency options of 450 kHz, 900kHz, or both. Utilizing self-adapting wave adjustment technology and advanced broadband signal processing, the system can clearly scan small objects and is ideal for a variety of high-definition underwater imaging applications, including cable and pipeline surveys, underwater archaeology, oil and gas, and environmental monitoring.
The lightweight and compact sonars are easy to integrate and can be connected via Ethernet or RS232 serial, and also provide 8 programmable TTL synchronous control outputs, solving common issues with acoustic interference and synchronization control.
The ES Series is available in four different variants to suit a range of user requirements.
