Copperhead is built from a MiniSAR, or Miniaturized Synthetic Aperture Radar. MiniSAR works by sending out a microwave pulse, reading the reflections of that pulse, and then stitching them together into an image. Copperhead took this technology and added in an algorithm that keeps the entire field of view in the same scale. Previously, MiniSAR had a problem plotting slopes, which limits the technology's usefulness in over mountainous terrain. Additionaly, because MiniSAR is a radar technology, it can see through smoke, dust, and weather. Dust and hills aren't ideal lab conditions, but they're very much battlefield ones.
