Pisces, the reason I selected ‘surface bounce’ equal to zero was just to simplify the display. I assumed that surface refection would only become relevant in the creation of the 2nd. CZ. I was only interested in following the rays travelling down from the source into the deepsound channel and returning to the surface (1st. CZ). If I had surface bounce on the display became confused due to rays that did not penetrate below the layer but instead bent back towards the surface, reflected etc. etc.
So it was a ‘more out of interest’ experiment to compare the DW SSP data against SoundPropagate utility and I was interested to hear the views of others.
As it is being said, the SSP values being displayed in the sonar station are most likely only cosmetic and I am sure that the actual simulation of CZ in DW may be so simple as to just intensify sound level every 30 nautical miles. But I suppose this is only reasonable, as with a full simulation we would not have had resources (PC) available for much else.
You know, it is always fun to dig about.
So I look forward to the improved SoundPropagation.exe from Dr. Sid and any enlightenment as to the sonar model used in DW.
