I’ve done the programming and the math and it can be done. However, it’s voodoo magic and it’s not what you think it will be. The sensor gives a distance that is too inaccurate and that makes locating the strike almost impossible.
I’ve looked at hardware used to study lightning and it cost more than my house. Most U.S. universities that have a program to study lightning have the equipment loaned to them. If it fails it is replaced at not cost to the university.
It’s like the military losing a million dollar aircraft. It’s replaced and very few people care. The Tempest will never be able to give us distance and direction.
