DS1800

Be brave in innovation and explore the ocean


‍DS1800 series miniature forward-looking sonar‍

The DS1800 ultra-high frequency forward-looking sonar is currently the highest frequency forward-looking sonar in our company's product line, which can provide near optical imaging resolution and is specifically used for close range high-precision imaging, such as detecting close range targets, close range observation, etc. It can replace optical imaging in turbid water bodies.


This sonar provides a domestically produced version with all components, and also offers models with a maximum working depth of 4km.

DS1800 Technical Parameters

Center frequency: dual frequency; The conventional frequencies are 1.8MHz and 2.7MHz; Other frequencies can be customized;


Range: 1-30m, continuously adjustable;


Distance resolution: 2.5mm;


Refresh frequency (range related):>10Hz;


Equivalent number of beams: 256;


Transmission signal: CW or CHIRP, automatic or manual selection;


Maximum working water depth: 300m;


Maximum working speed: 6kn. Exceeding this speed has no impact on usage, but may reduce the detection distance (design specifications);


Work blind spot: ≤ 0.1m;


Imaging quality: The intensity of the target and artifacts is greater than 30dB (design specification);



Detection distance, center beam width, and opening angle (maximum detection distance for strongly reflective targets such as rocks, coasts, etc.; small target detection distance for targets with a reflection intensity of -20dB; clear water quality, flat sediment bottom, good or moderate hydrological conditions, and sailing speed<6kn)：
