A news of today is that a Russian satellite used as target for a missile test is exploded, generating myriads of small fragments that could, due to their orbit, constitute a danger to the International Space Station.

I wonder if it would not be better for this type of test to use special inflatables.

The inflatable target, upon departure, could be housed in a small space, using a small rocket or it could be "housed" in a larger carrier as a secondary payload.

Once in orbit it would inflate reaching dimensions compatible with those of a satellite target of an attack. At this point, once reached by the missile during the test, it would generate a few fragments once exploded, most of which are not dangerous.

Are there technical problems that do not allow this solution for these kind of military experiments?

See ASAT ITV or Instrumented Target Vehicle:
The Instrumented Target Vehicle was a relatively sophisticated active satellite. Battery powered, the balloon satellite remained inert and uninflated in orbital storage until the inflation command was transmitted to it. This would only come minutes before the intercept test, and was given as the satellite passed over a Hawaiian ground station. This would set the target up for an intercept over the California coast by an ASAT launched by an F-15A from Edwards AFB.

While an inflatable target might help, it is not so much the material of the impacting object (e.g. fragments of a balloon) that will cause the damage, as the kinetic energy of the object itself.

I think most of us would agree that straw is lightweight, easy to bend etc. etc. Just look at pictures of straw embedded in telephone poles after tornados or hurricanes have passed by, and even a high end tornado or hurricane gust is only going about 300 mph.

The issue is not one of using targets and weapons that produce less debris.

How many economies have invested in, and come to rely upon, space-dependent technology in the form of navigation and data transfer with the assumption that these technologies are safe and reliable?

We use STEM and the reassurance that space technology is the way forward, to get schools and universities to invest in the advancement of space, we listen to governments spruik their reasoning why investment in space is a worthy cause, and how multinational cooperation can only be a good thing while planning and developing ways to disrupt the whole system at a moment's notice is considered justifiable.

How many new satellites have been launched in the past 10 years under the belief that the risk of collision is acceptable given the current technology and understanding of the problem, and yet again someone has decided to throw a fist full of debris in amongst the field of play? Yet any one of the proponents who have conducted a "test" of anti-satellite weapons would be quick to complain if one of their satellites were disrupted by a test conducted by the other "side."
