Disappearing contacts
2022.1 Patch 11
Hydrophone detects propeller noise too far to intercept submerged. I surface and head towards the estimated location anyway. Nothing seen on visual scans. I submerge again and hydrophone picks up noise behind me in a location I passed through on the surface. This pattern seems to repeat.
I'm wondering if the hydrophone is detecting distant noise due to a convergence zone, which is why they seem to be phantom contacts?
