Forgive me if I am repeating anything, but just to be clear.....

When the mission starts, the game counts ground objects inside the Target 'circle' and calculates how many must be detroyed based on the destruction percentage. If you have 8 objects in the circle at mission start and the objective is set 50%, the game decides you need to destroy 4 objects inside the circle.

If at some point 6 moving objects leave the circle, the objective is impossible to achieve as there are only 2 targets to destroy.

Similarly, if other moving objects arrive within the circle at the time of attack, the objective may become easier. The game does not distinguish between objects that were in the circle at the time it makes the initial objective calculation and objects that arrive or leave later. It requires you to destroy a sufficient number of objects that are within the circle at the time they are destroyed to satisfy the target number it calculated at mission start. It doesn't care if they are the same objects that it used in the calculation or different objects.
