The spectral analyzer and direction indicator (SADI) system is an electro-optic sensor that can determine both the spectral content and direction of the source of a single pulse of radiated energy. In its simplest form, it can determine the direction of the source in one dimension. Directional information in two dimensions requires the addition of some electronics and, in some configurations, optics. Various degrees of electronic processing sophistication may yield the pulse shape, and its spectral and spatial distribution.
