M3 Sonar Sonar Processor In this publication, the computer can also be referred to as the Processor Unit, and vice versa. The Sonar Processor contains the operational software, and offers the user interface that allows you to control the M3 Sonar. It is a vital part of the M3 Sonar system. The Sonar Processor runs the M3 software that manages communication with the Sonar Head, performs all beamforming and image processing and presents the sonar...
Page 16: Sonar Head
M3 Sonar Reference Manual Sonar Head When deployed underwater, the Sonar Head transmits and receives acoustic pulses. The Sonar Head includes transmit and receive transducers and the electronics to generate the transmit pulse and digitize the received signal. The sonar data is sent to the Sonar Processor using a standard Ethernet link.

Page 23: Restoring Usb Driver Functionality In Windows 10
Getting started Restoring USB Driver Functionality in Windows 10 If you are using Windows 10, a new security feature may cause your system installation to fail, especially if you are using a USB port in your system. For example, a USB port is used to interface with a security key inserted into the USB port, or an Interface Unit connected via the USB port.
Page 24: Installing The M3 Software
We recommended installing the latest M3 software on your Sonar Processor. Prerequisites • You can find the software on the Kongsberg USB drive included with the system, or you can contact your local dealer or distributor to have the latest software version installed.
Page 25: Defining The Ip Address On The Computer's Network Adapter
Getting started Defining the IP address on the computer's network adapter The communication between the Sonar Processor and the Sonar Head is made using a high-speed Ethernet cable. If a Sonar Processor is not configured to connect to the sonar, you must define which IP Address and Subnet mask the Ethernet adapter in the Sonar Processor shall use for this communication.
Page 26: Changing The Frequency
M3 Sonar Reference Manual Changing the frequency If you have a high-frequency M3 Sonar transducer, you can change the frequency using Display Widget Context Note The frequency buttons will not appear if you are using a 500 kHz transducer. In addition, these buttons will not appear in playback mode.

Page 29: Testing The Sonar Head Telemetry
Getting started Make sure there is no acoustic or electrical interference in the sonar view. Make sure that no concentric rings appear. These rings could be caused by other acoustic devices or power-line noise. Rings with black gaps between them could also be due to excess Ethernet traffic when using a shared network.
Page 30 M3 Sonar Reference Manual by selecting the appropriate sonar application and adjusting the Ethernet adapter settings to the corresponding link speed. Note There are no standard sonar applications with a telemetry-link speed requirement higher than 100 Mbps. The ping rate is normally taken from the sonar application or range setting. If the estimated available bandwidth is less than the bandwidth required by the sonar application/range, the M3 software reduces the ping rate to compensate.
Page 31 Getting started Observe the graph to determine the average network link speed. An average link speed of at least 80 Mbps is required by most sonar applications (some applications and range scales will use less). A link speed of less than 80 Mbps may result in a slower than expected ping rate.
Page 32: Testing 1Pps Time Sync Mode
M3 Sonar Reference Manual Testing 1PPS Time Sync Mode If you have an M3 Sonar Head with a 1PPS connector, you can synchronize the Sonar Head clock with an external 1PPS source. After you have enabled the 1PPS Time Sync Mode, you can make sure it is working by reading through the log file.

Page 111 Menu system The following sonar applications are available when using a 500-kHz Sonar Head transducer. Description • This sonar application captures high-quality images. At short ranges the images are relatively insensitive to the motion of the sonar. At longer ranges the sonar should be relatively motionless.
Page 112 M3 Sonar Reference Manual Use this sonar application primarily for profiling using a 3-degree Tx vertical beamwidth. You may also use this application for shallow-water obstacle avoidance. • Imaging 30 You can use this sonar application for navigation and obstacle avoidance. This application uses a 30-degree Tx vertical beamwidth.

The greater the distance between the transducer and the target(s), the greater the loss of energy. (Time Variable Gain) compensates for the loss of acoustic energy due to geometric spreading and absorption.
Page 203 Functions and dialog boxes • Geometric spread Once transmitted, the acoustic energy will spread out to form a circular beam. The width of this beam increases with the physical distance to the target(s). • Absorption loss Depending on the salinity and temperature, the water will absorb some of the energy from the acoustic transmission.
