On the subject of stealth, I've always wondered if stealth aircraft could not actually be detected fairly easily. True, stealth aircraft have an extremely small radar cross-section. But I'm guessing they also have very specific and recognizable radar signatures, with the proper signal treatment, despite high noise ratios, their signatures could be isolated. And they could also be easily identified down to the variant of aircraft. This is a pure guess, not substantiated by anything, and I'm far from an expert or even an enthusiast in the field.
