MiniUAC-1203 Small Forward-Looking Sonar
Most Balanced Performance Multibeam Forward-Looking Sonar (FLS)
The MiniUAC-1203 series miniature forward-looking sonar is a two-dimensional forward-looking multibeam imaging sonar. It provides forward acoustic vision for platforms operating in both clear and turbid waters, enabling target detection and identification, collision avoidance, and obstacle detection.
Compared with similar products available both domestically and internationally, this sonar offers superior performance, a wider range of operating frequencies and functions, smaller size, lower power consumption, and a competitive price. In addition, most configurations are available from stock for long-term supply. For configurations not currently in stock, the typical delivery time is within one month.
The MiniUAC-1203EL, currently on sale, represents the latest generation of the MiniUAC-1203 series. Compared with the previous generation, it features a higher frame rate, upgraded connectors with improved pressure resistance, and reduced size and weight. The MiniUAC-1203EL also supports an optional passive direction-finding function, allowing the sonar to rapidly scan sound sources within a specified frequency band and estimate their bearing.
The currently available operating frequencies include single-frequency configurations at 375 kHz, 700 kHz (collision avoidance), and 900 kHz, as well as dual-frequency configurations of 400 kHz / 700 kHz, 750 kHz / 1.2 MHz, 1.2 MHz / 1.8 MHz, and 1.2 MHz / 2.1 MHz.
