The Soviets allegedly used the same principle to make cheap single sensor missile seeker heads.
Two DOF: two sensors?
If the missile is spinning, you can do it with one. The original Sidewinder air to air missile worked that way.
Neat, thanks. I should have thought of that.
And now the name 'sidewinder' makes perfect sense
While it may have been a secondary reason, it's named after the snake for the sensory "heat seeking" attribute: https://en.wikipedia.org/wiki/Crotalus_cerastes
I had always assumed it was due to the use of roller stabilized fins / rollerons.
