WIDEBAND INTERFEROMETRIC SENSING AND IMAGING POLARIMETRY 2
ABSTRACTIn this overview, reasons are provided on why we do need to place multi-
modal, multi-band single and multiple pass POLinSAR monitoring
platforms into air and 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
POL-IN-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 around monitoring of
the terrestrial covers are analyzed in view of the un-abating and
uncontrollable terrestrial population explosion, which has, does and for
ever will result in unavoidable conflicts deteriorating unfortunately at
times into terrorism. The pertinent questions on how to reduce the
exorbitant cost for initiating this “home-globe security protection”
technology are therefore also broached, and the expected benefits are
laid out. 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 fleets of orbiting multi-band space-borne
POLinSAR platforms are urgently required.

Brief introduction of DIFF-RP-IN-SAR
• Three-pass “repeat track” interferometry uses
two baselines to acquire
interferograms at different times.
• Despite exaggeration in picture on the right,
the incidence angles and absolute ranges are
nearly the same.
• Now suppose that the surface deformed
slightly between the second and third
acquisitions in such a way that the range
changed by an amount
• In the repeat-track implementation of
interferometry, the signal travels each path
twice, since the transmitter and receiver are in
the same place. Therefore, the
interferometric phase is
(B1,1); (B2 ,2)

ACQUISITION OF NEW BANDS FOR BOTH PASSIVE & ACTIVE SENSING

Biomass and vegetative cover estimation HF – EHF (P/L/C-Band)
Man made surface structure monitoring HF – EHF (C/X/K-Band)
Atmospheric passive remote sensing cm – sub-mm
◊ We need to put our act together as the global remote sensing community and request from
ITU/WMO the protection of the “fundamental natural resource: the e-m spectrum”, and for
providing the spectral bands for us to fulfill our professional duties as
“The Remote Sensing Pathologists and Radiologist of the Earth and Planetary Covers”

THE IMMINENT COLLISION:
Passive vs Active Spectrum Users, e. g. radio-astronomy vs global telecommunications complex
◊ CLEAN THE PROPAGATION SPACE FROM PROPAGATION LITTER:
- users not requiring free propagation space must be relegated
to the use of the global EO fiber transmission network
◊ PRESERVE THE GLOBAL NATURAL RESOURCE – THE E-M SPECTRUM FROM MISUSE:
- misuse of spectral band acquisition by aggressive
telecommunication complex must be put to an end
◊ ASSIST AERONOMISTS AND RADIO ASTRONOMERS IN ESTABLISHING THE
BACKGROUND NATURAL NOISE SIGNATURES OF TERRESTRIAL, PLANETARY AND
GALACTIC ORIGIN
- establish natural background signatures in all spectral bands
◊ THERE DOES NOT EXIST A SINGLE SPECTRAL BAND IN WHICH THE TERRESTRIAL
COVERS DO NOT POSSESS DISTINCT EIGEN-RESONANCES
- the measurement and monitoring of natural eigen-resonances is essential for natural hazard
prediction and mitigation – short term and long term
