SYSTEMS AND METHODS FOR AN IMPROVED MULTIBEAM IMAGING SONAR FOR USE WITH AN UNDERWATER HANDHELD COMPUTER
A system comprising: at least one hardware processor; and one or more software modules are configured to, when executed by the at least one hardware processor, receive a selection of a mission marker; display a diver's position, heading, depth and course history for the selected mission marker; and interface with a multibeam imaging sonar that uses a 12 degree aperture on a 750 k frequency band to improve the resolution and clarity of the sonar image, as the narrow beam width allows for more precise targeting and detection of objects.
1 . An underwater handheld computing system comprising:
a display;
at least one hardware processor; and
one or more software modules are configured to, when executed by the at least one hardware processor,
receive a selection of a mission marker;
display a diver's position, heading, depth and course history for the selected mission marker on the display; and
interface with a multibeam imaging sonar that uses a 12 degree aperture on a 750 k frequency band to improve the resolution and clarity of a sonar image displayed on the display (sonar display), using a narrow beam width that allows for more precise targeting and detection of objects.
2 . The system of claim 1 , wherein the sonar display comprises a plurality of sonar color palettes.
3 . The system of claim 1 , wherein the underwater handheld computer is further configured to:
display the diver's position and speed over ground;
the height of the diver above the seabed;
pressure sensor data; and
water column depth.
4 . The system of claim 2 , wherein one or more software modules are configured to, when executed by the at least one hardware processor, enhance the visualization of data displayed using the plurality of sonar color palettes.
5 . The system of claim 4 , wherein one or more software modules are configured to, when executed by the at least one hardware processor, use the color palettes to highlight different features of a displayed sonar image, making it easier to identify and interpret.
6 . The system of claim 4 , wherein one or more software modules are configured to, when executed by the at least one hardware processor, use the plurality of color palettes to help the user to distinguish between different types of underwater objects, such as rocks, coral, and manmade objects, which have different acoustic properties that are reflected in the sonar image.
7 . The system of claim 1 , wherein one or more software modules are configured to, when executed by the at least one hardware processor, display last known date, time, location of a magnetic heading calibration, and the diver's depth.
8 . The system of claim 1 , wherein one or more software modules are configured to, when executed by the at least one hardware processor, display a pinger locator feature.
9 . The system of claim 1 , wherein the underwater handheld computer system comprises a heads up display to mirror the data displayed on the display.
10 . The system of claim 1 , further comprising a bezel made of Beryllium Copper (BeCu) to reduce the magnetic signature.
11 . The system of claim 1 , further comprising a 300 Wh Lithium Ion battery pod or a 97 Wh Lithium Ion battery pod, and a Lithium Ion battery charger.
