UWR System Chassis (IMAGE) Southwest Research Institute Caption SwRI engineers set up a developmental chassis for the ultra-wideband (UWR) receiver. The UWR system, which contains powerful signal acquisition algorithms, achieves “constant staring” over the entire electromagnetic warfare frequency range using a single processing card, visible here in the center, marked by two small green lights.
