Future perspectives of SAR polarimetry with applications to multi-parameter fully polarimetric POLSAR remote sensing & geophysical stress-change monitoring

With the un-abating global population increase our natural resources are stressed as never before, and the global day/night monitoring of the terrestrial covers from the mesosphere to the litho-sphere becomes all the more urgent. Microwave radar sensors are ideally suited for space imaging because those are almost weather independent, and microwaves propagate through the atmosphere with little deteriorating effects due to clouds, storms, rain, fog and haze. Globally humidity, haze and cloudiness are increasing at a rather rapid pace for irreversible reasons due to expansive aerosol build-up within the tropical/subtropical belts. Thus, optical remote sensing from space especially in the tropical and sub-tropical vegetated belts will become rather ineffective, and microwave remote sensing technology must now be advanced strongly and most rapidly hand in hand with digital communications technology because operationally radar sensing is more rapidly available especially for disaster mitigation assistance.
