Passive interfering method for insar based on circularly moving strong scatterers

InSAR Forensics: Tracing InSAR Scatterers in High Resolution Optical Image

The current synthetic aperture radar (SAR) theory makes a quite restrictive assumption – linearity – in the SAR imaging model, for the convenience of mathematical derivation. That is to say the imaged area is considered as an ensemble of individual point scatterers whose scattered fields and, hence, their responses in the SAR image superimpose linearly [1]. This is the so called the first Born ...

Phase diagram for passive electromagnetic scatterers.

With the conservation of power, a phase diagram defined by amplitude square and phase of scattering coefficients for each spherical harmonic channel is introduced as a universal map for any passive electromagnetic scatterers. Physically allowable solutions for scattering coefficients in this diagram clearly show power competitions among scattering and absorption. It also illustrates a variety o...

Multi-temporal InSAR analysis of Wenjiagou Landslide using Distributed Scatterers

Phase diagram to design passive scatterers

A phase diagram, defined by the amplitude square and phase of scattering coefficients for absorption cross-section in each individual channel, is introduced as a universal map on the electromagnetic properties for passive scatterers. General physical bounds are naturally revealed based on the intrinsic power conservation in a passive scattering system, entailing power competitions among scatter...
