Target and Clutter Scattering and their Effects on Military Radar Performance: Electromagnetic Wave Propagation Panel Specialists Meeting Held in Ottawa, Canada on 6-9 May 1991 (Diffraction par les Cibles et le Fouillis et ses Effets sur les Performances des Radars Militaires)
Abstract
Radars have been used for target detection and identification for many years. Their performance is chiefly limited by clutter. New techniques in high resolution radars, millimeter wave systems, polarimetric analysis, bistatic radars, adaptive filtering are being developed. Recent advances in computing speed have enhanced enormously the radars' capability in differentiating targets from clutter. But ultimate performance of these new systems depends on more complex knowledge of clutter and target scattering. Efforts for improving models and their experimental verification are underway concerning the clutter and target characteristics and their impact on radar systems. These issues were addressed during the symposium in the following topics: Models for surface scattering; ground and sea clutter. Models for volume scattering: atmospheric, ionospheric, chaff. Models for target scattering; RCS reduction or modification techniques. Methods of experimental characterization of clutter and targets: calibration procedures. Combined scattering and propagation effects on system performance. Processing for target to clutter enhancement: coding, and modulation, adaptive beam forming and nulling; polarimetric techniques, imaging, interferometric techniques. Processing for target identification. Practical signal processing implementation techniques.
