Can you verify this as an example...
Towed array
True bearing 090
ambiguious bearing 270
Sphere array
True bearing 090
ambiguious bearing 270
????
or just that you get a narrowband tonal at 090? The TA picks up lower frequencies while the sphere picks up higher frequencies. |
Here's the sequence:
1) There is no contact on the broadband sphere array (not even a faint line)
2) I get no contact profile in the UPPER narrowband sphere array screen BUT I do get NARROWBAND LIBRARY PROFILES in the LOWER narrowband sphere array screen when the cursor is on both towed array bearings... |
This might be that you do have a contact with a very faint and distant lower end tonal of 50 or 60hz. One of the ppl here has a sonar screenshot to adjust your settings so that you can see that faint tonal.
