Why we do need to place Multi-Band Single and Multiple Pass POLinsSAR Monitoring Platforms into Space

The ESA POLinSAR Workshop on “Applications of SAR Polarimetry and Polarimetric SAR Interferometry” is arranged at the ideal time for developing this urgently required technology for environmental stress-change and local-to-global conflict monitoring in air and specifically in space. In this overview, reasons are provided on why we do need to place multi-modal, multi-band single and multiple pass POLinSAR monitoring platforms into space. The questions “on what POLinSAR monitoring can provide that POL-SAR and IN-SAR by themselves cannot accomplish” is assessed; whereupon facts and justifications on placing POLIN-BISAR satellite clusters into space are presented. Reasons for this technology becoming a basic requirement for current, near-future and much more so for future all-day & night year’round monitoring of the terrestrial covers are analyzed in view of the un-abating and uncontrollable terrestrial population explosion. The pertinent questions on how to reduce the exorbitant cost for initiating this “home-globe security protection” technology are also broached, and the expected benefits are laid out in detail. The pertinent National and International airborne and space borne multi-modal, multi-band SAR remote sensing and security conflict surveillance support agencies are herewith invited for co-sponsoring our proposal, which is timely and POLinSAR platforms are urgently required to be placed into space.
