This is known as a line-drawing algorithm. That link has multiple algorithms to solve this problem - for your case you'll want to ignore the algorithms which anti-alias. The simplest solution is the naive algorithm:
dx = x2 − x1
dy = y2 − y1
for x from x1 to x2 do
y = y1 + dy × (x − x1) / dx
plot(x, y)

Check if the point you get is on the far half-circle, and if it is, mirror it.
Radius = 5;
_randomDirection = (Vector3)(Random.insideUnitCircle).normalized;
Vector3 toTarget = _target.position - _source.position;
if (Vector3.Dot(toTarget, _randomDirection) > 0f) {
_randomDirection = Vector3.Reflect(_randomDirection, toTarget);
}
Vector3 ...
