Microlocal analysis of Radon transforms over quadric surfaces
Gaik Ambartsoumian, Raluca Felea, Venkateswaran P. Krishnan +2
We study the microlocal properties of generalized Radon transforms over a family of quadric hypersurfaces whose centers lie on an orientable hypersurface . The quadric surfaces…
Artefact Analysis of Multistatic Three-Dimensional SAR Imaging with Two Linear Trajectories
Daniel Andre, Venky P. Krishnan, Clifford Nolan
In recent years, radar technology has seen much improvement, making multistatic Synthetic Aperture Radar (SAR) sensing a realistic possibility, for example in satellite constellati…
Mitigation of Artifacts in Multistatic & Passive Radar Imaging Using Microlocal Analysis
David McMahon, Clifford J. Nolan
In the analysis of many synthetic aperture radar (SAR) experiments the possibility of passive background signals being recorded simultaneously and corrupting the image is often ove…
A class of singular Fourier integral operators in synthetic aperture radar imaging
G. Ambartsoumian, R. Felea, V. P. Krishnan +2
In this article, we analyze the microlocal properties of the linearized forward scattering operator and the normal operator (where is the adjoint of $F…
