Hi,
I'm currently in the process of implementing a first prototype of a broadband sonar for my subsim.
Have a look at this picture:

I'm currently struggling how to best implement the background noise (random noise of the ocean, in the picture those are the dark grey random points)...I'm sure there are standard algorithms/maths to do that.
Can anybody help me here ?
Thanks.
