Development of new multi-band equatorially orbiting POLinSAR satellite sensors system configurations for varying latitudinal coverage within the tropical belt

With the relentless increase in population density, the anthropogenic expansion into natural terrestrial hazard zones has become irreversible resulting in ever more catastrophic disasters within the entire tropical belt engulfing Mother Earth. Thus not only the Indonesian-Pacific Islands, so also South America, Africa and back via the Indian Ocean Islands to Asia-Pacific, these natural events like volcano eruptions, earthquakes with emerging tsunami, cyclones and severe down pours have caused havoc, loss of lives, destruction of infrastructure and above all intentional manmade interference resulting in the deterioration of pristine tropical jungle forests. What is required is around-the-clock local and wide-area surveillance and remote sensing of the vegetative cover for which first well designed optical equatorially orbiting satellite sensors had been developed but their successful implementation failed because of the ever increasing cloud, precipitation, humidity and aerosol cover within the entire equatorial belt of +/- 12* per one-day revisitation, within Tropics-belt of ~ +/- 23.7* latitude rendering penetration at optical wavelength mostly ineffective. Hence, we must take recourse to microwave sensing, and implement radar and synthetic aperture sensors from air and space operational at day & night independent of weather; and the sensors especially suited are the fully polarimetric POL-SAR sensors developed for satellite remote sensing by the major SAR technology development centers worldwide.
