A detailed analysis of higher order Doppler effect, due to multiple electromagnetic field reflection upon the two moving objects is performed, invoking the center of momentum frame and taking all possible range of velocity into account. A quasi-stationary based finite difference time domain numerical method is then performed in order to test the proposed mathematical model for forward scattering analysis. Further, a spectral-temporal mathematical derivation is performed for the inverse scattering analysis to compute the spatial and temporal information of the target system.

The proposed algorithm uses the scattered field pattern and an inverse scattering technique derived from Green's function to retrieve the geometry of an unknown target. This method uses the scattering field data over a band of observation points, which is synthesized using frequency domain "method of moment" computational technique. We have verified this algorithm with four different types of numerical examples. K E Y W O R D S field curvature method, inverse scattering, method of moment, microwave imaging

The Finite Difference Time Domain method (FDTD) is used to simulation a forward scattering model to generate scattering field measurement data. For inversion multi scattering depth imaging technique is utilized, which is a non-destructive linear time domain approach. The objective of this technique is to find out permittivity profile of the target over time.

This area of research also extended to work with the dynamic object where the objective is to retrieve velocity profile along with its general properties. Here we represent all the major development done in electromagnetic inverse scattering both in static and dynamic platform since last four decades both in time and frequency domain with its working principle, advantages, and its limitations. We also provided a comprehensive discussion of the basic theory of inverse scattering analysis both in the static and dynamic domain. KeywordsInverse Scattering; Microwave Imaging; Electromagnetic Forward Scattering; Terahertz Imaging; Moving Target Imaging; Radar Imaging; Non-Relativistic Imaging.
