Low, Slow, and Small Targets Explained

Low, slow, and small targets are one of the central problems in low-altitude security. The phrase is often used in counter-UAS discussions because many small drones do not behave like conventional aircraft. They may fly close to the ground, move slowly, hover, follow buildings or terrain, and present only a very small physical and electromagnetic signature.

That combination is what makes the problem difficult. A target can be easy to describe in a meeting and still be hard to detect reliably at a real site. A small quadcopter near a roofline, a tree belt, a fence, or a busy service road is not just a smaller aircraft. It is a weak, low-altitude, often intermittent signal inside an environment full of other movement and reflections.
