Will be of great help to all players of RA.
It 's very clear the issue of the cones acquisition and the influence on the scope of aspect angle.
I do not understand how the Sea State and Bottom influence the extent of the sensors. The mathematical model of how it works?

Sea State - gives the large background of noise.It is most difficult to allocate a useful signal from noise of a component.
You throw a stone in quiet water - will see well as the circles propagation on water.
Also throw a stone in rough waters. You will not see clearly any more these circles - waves mix them.
Bottom - does not give waves wide propagation. Sand or Mud - the sound waves do not reflect and absorb them. (The reflection is - but very, very weak. It is more absorption)
It as you throw a ball on a HARD floor - he will jump up some times.
And if to throw a ball on a SOFT sofa or bed - he will not jump up.
Similar and with sound propagation.
