Paper Abstract

`WISIP: Wideband ((mu) Hz - PHz) Interferometric Sensing and Imaging Polarimetry' has become an important, indispensable tool in wide area military battlespace surveillance and global environmental stress change monitoring of the terrestrial and planetary covers. It enables dynamic, real- time optimal features extraction of significant characteristics of desirable targets and/or target sections with simultaneous suppression of undesirable background clutter and propagation path speckle at hitherto unknown clarity and never before achieved quality. `WISIP' may be adopted to the Detection, Recognition and Identification (DRI) of any stationary, moving or vibrating target or distributed scatterer segments versus arbitrary stationary, dynamically changing and/or moving geo-physical/ecological environments, provided the instantaneous 2 X 2 phasor (Jones/Sinclair) and 4 X 4 power density (Mueller/Kennaugh) matrices for forward- propagation/backward-scattering, respectively, can be measured with sufficient accuracy. For example, the DRI of stealthy, dynamically moving and/or camouflaged stationary objects occluded deeply into heterogeneous stationary and/or dynamically moving inhomogeneous volumetric scatter environments such as precipitation scatter, the ocean sea/lake surface boundary layers, the littoral coastal surf zones, pack-ice and snow or vegetation canopies, dry sands and soils, etc., can now be successfully realized. A comprehensive overview is presented on how these modern high resolution/precision, complete polarimetric coregistered signature sensing and imaging techniques, complemented by full integration of novel navigational electronic tools, such as DGPS, will advance electromagnetic vector wave sensing and imaging towards the limits of physical realizability. Various examples utilizing most recent image data take sets of the NAWC/ERIM-P3-UWB-TOPIF'E-CATI/LTBL- POLSAR and NASA-JPL-AIRSAR airborne, the NASA/DARA/DASI-SIR- C/X-SAR shuttle, and the ESA ERS-1/2, JERS and RADARSAT satellite imaging systems will be presented for demonstrating the utility of WISIP.
