Forward Scan Sonar For Ships


This mod adds a sonar to the game which you can use from any ship. This can be useful if you have ever unintentionally grounded your ship or crashed into underwater objects. Also it can be used for searching for objects at the sea floor.

Modes of operation

Sector Imaging Mode - scans a 180 degrees sector with a very narrow vertical beam. Signal strength is mapped to display intensity, displayed range is not corrected (slant range). This is best suited for searching for objects on the sea floor and for making images.

Sector Depth Mode - scans a 180 degrees sector with a wider vertical beam. Depth of each point is mapped to display color, displayed range is projected. This mode is more useful for navigation in shallow areas.

Basic Forward Scan Mode - scans area directly ahead of your vessel with a vertical beam. Position of each point is displayed on distance-depth graph, giving you precise information of depth right ahead of your vessel. Although you can see only a small area of the sea floor, this mode has the fastest refresh rate.

* Wherever the depth is displayed in the device, it is not the true depth, but depth below sensor position which is located at the bottom of your vessel.
* Sector scanning modes might degrade your frame rate. If you are having bad performance, reduce the scan rate.

How to enable
When you are in a ship, use the "Sonar Options" action in the action menu.


Mode - sets the mode of sonar.
Range - sets the maximum range of the sonar.
Max Depth - sets the depth limit for the display. Only affects basic forward scan and sector depth modes.
Image Gamma - Allows you to adjust gamma correction of the image. Only affects sector imaging mode.
Scan Rate - Allows you to adjust the scanning rate of the sonar. Only affects sector imaging and sector depth modes.

oh wow you actually have done it before thats awsome!

Ok, so you mean just a radar to scan terrain. I've tried it, looks pretty fun:
But I don't know how it matches real devices of this kind, and what would be the use of it in the game.

yes i meant radar for overground
that buoy thing would be nice though if you still mod

Radar doesn't penetrate under water.
And IRL they deploy buoys from helicopters to scan for submarine sounds. The only way for a device to perform an acoustic scan is by being submerged into the water.

maybe but i meant so you can scan from under helicopters for things like anti sub warfare - do you know if theres a thing like this for radar already?

Like a sonar buoy deployable from helicopter?

(yes i mean underwater)

Hey amazing mod! Would it be possible to have something like this just for helicopters?
