Pretty neat trick.

I guess you are using the circle to determine the range of the target at each of the three bearing surveys.

When I play with map updates on, the hydrophone results shows both bearing and distance...do you not get a distance reading the the hydrophone without map updates?
If not, can you eventually learn the distance to a target by the volume of the sound of its propellers?
