| Definition | A shallow water multibeam echo sounder. high resolution mapping and inspection application As an option the EM 2040P can be delivered with the dual swath capability, allowing a sufficient sounding density along track at a high vessel speed. Also optionally, the sonar head can be delivered with mounts for motion sensor and sound speed sensor, factory aligned for ease of mounting. The operating frequency range is from 200 to 400 kHz. The operator can choose the best operating frequency for the application: 300 kHz for near bottom, 200 kHz for deeper waters and 400 kHz for very high resolution inspection. The system has an output sample rate up to 60 kHz. The system can effectively operate with very short pulse lengths - The shortest pulse is 14 microseconds, which gives a raw range resolution of 10.5 mm. The angular coverage for the 200 and 300 kHz is 140 degrees, allowing coverage of 5.5 times water depth. For the 400 kHz mode the angular coverage is 120 degrees. | |
