First FBP Animation The top view here is from one of the first
animated simulations made, 21 April 2013,
using Feature-Based Passive Wavar --
in which it is not the case that both the time and
the place of emission of a click are known.

Except for the choice of colors, this represents
what we expect to see when we input echoes
of the clicks of a dolphin into an echoscope.
The side view came from active sonar.

The array has 36 sensors in an hexagonal grid.
