摘要：A signal processor (30) for a submillimeter wavelength active radar system (10, 20, 30) processes signals received and downconverted by the radar system, the downconverted signals having a periodic component having phase and amplitude information which is dependent on content. Information about the content is discriminated from the phase and amplitude information in the signals. By using phase rather than only amplitude, there is additional information in the downconverted signals which is lost in a conventional non coherent system as being indistinguishable from noise. The phase is more sensitive to changes in the content such as objects, background and atmospheric conditions, than amplitude alone. The phase information can be characteristic of the content owing to content flutter, changes in submillimeter standing waves and interference fringes in received reflections of submillimeter illumination if surface layers have a thickness of a number of half wavelengths.
