Autonomous Balloon Controls for Protection against Projectiles with Known Destinations
This article tackles autonomous balloon controls for protection against projectiles with known destinations. We introduce a defense strategy against an enemy projectile trying to reach a destination, such as a military base, which is known a priori.
