  • Page 23: Introduction

    Current efforts are focused on the application of cutting edge chirp, DSP, and acoustic technology. 1.2 Product Overview EdgeTech’s 4600 is a combined, fully-integrated, swath bathymetry and side scan sonar system. The 4600 uses eight receive element transducers and one discrete transmit element to produce real-time, high-resolution, 3D maps of the seafloor, while also providing co-registered simultaneous side scan and bathymetric data.

  • Page 24: Supplied Components

    4600 Swath Bathymetry and Side Scan Sonar The 4600 operates at one of two frequencies, 230 kHz or 540 kHz, depending on the model. The sonar electronics and arrays are mounted onto a streamline body that is deployed over-the-bow (-or side) of a survey vessel. Sonar data is transferred from the transceiver to the processing unit on board, via an Ethernet network interface.

  • Page 64 4600 Swath Bathymetry and Side-Scan Sonar A few important things to know about basic bathymetry are discussed in items 1 through 4 and are highlighted in Figure 32. 1. If the Bathymetric Processing box is unchecked during real time acquisition, the system will act as a simple side scan system and will not compute or acquire any bathymetric solutions.
  • Page 65 4600 Swath Bathymetry and Side-Scan Sonar 4. The Minimum Processing Range acts like a blanking range but in terms of slant range. The sonar will not process any data until it has reached this slant range limit. The default value is set to 1 m. Typically this parameter is not adjusted unless the user is surveying within constant deep water (greater than 50 m).

  • Page 70 PROCESSOR should only use the port or starboard side only to compute the seafloor depth. For instance, if the 4600 is mounted on the side of a survey vessel, there is the possibility that the 4600 will observe one or more hull echoes on its side facing the boat.
  • Page 71 4600 Swath Bathymetry and Side-Scan Sonar BATHYMETRIC PROCESSOR would ignore these points and search for the points that had the lowest amplitude. The bottom track function would then lock on to those lowest amplitude points, (which is hopefully the bottom) and track these accordingly.

  • Page 83: Frequently Asked Questions

    Where is the best place to mount the 4600 Sonar Head on the survey vessel? The bow of a survey vessel is always the best place to mount the 4600 Sonar Head. By placing the system at the bow, the sonar will most likely be far enough away from most interferences such as hull echo(es), propeller noise, wake, etc.
  • Page 84 Why can’t I feed navigation directly into the Topside Computer? In order for the 4600 to properly process the bathymetry data, it needs all of the supporting information, such as position, heading, roll, pitch, and heave. inputting the supporting device directly into the computer poses a risk of mismatching time stamps.
  • Page 85 Service using the information provided on page x of this manual. [13] Can the 4600 System measure pilings or vertical objects? The 4600 system can measure vertical objects, if configured to do so. Currently, the system acquires data that is then binned and averaged according to a specified number of horizontal bins.
  • Page 86 Check to see if DISCOVER is connected to your Third Party Software following the directions stated in Section 5.2.2. [18] The 4600 system connects with Hypack and Triton, why doesn’t connect with other topsides? EdgeTech has approved a small number of Third Party Topsides for acquisition and processing of the bathymetry and side scan data.
