  journal={SIAM J. Imaging Sci.},
We consider imaging of fast moving small objects in space, such as low earth orbit satellites, which are also rotating around a fixed axis. The imaging system consists of ground based, asynchronous sources of radiation and several passive receivers above the dense atmosphere. We use the cross-correlation of the received signals to reduce distortions from ambient medium fluctuations. Imaging with correlations also has the advantage of not requiring any knowledge about the probing pulse and… 

SelfieStick: Towards Earth Imaging from a Low-Cost Ground Module Using LEO Satellites

Real-time access to overhead Low-Earth Orbit (LEO) satellite imagery from a handheld device can have transformative applications: tracking wild-fire, natural disasters and weather events. Today,



Tracking Low Earth Orbit Small Debris with GPS Satellites as Bistatic Radar

Space debris is a growing problem and collisions are potentially lethal to satellites. Trajectories for small objects are predicted based on infrequent measurements, and the scale and therefore cost

High-Resolution Interferometric Synthetic Aperture Imaging in Scattering Media

A high-resolution interferometric method for synthetic aperture imaging through an unknown scattering medium which distorts the wave shows that, while mitigating the wave distortion, it is possible to obtain a robust and sharp estimate of the modulus of the Fourier transform of the reflectivity function.

Atmospheric turbulence has been shown to have measurable effects on several aspects of radar performance. In this paper we discuss the perturbation of the angle-of-arrival (AOA) of radar beams caused

Passive Imaging with Ambient Noise

The authors present, for the first time in book form, a self-contained and unified account of correlation-based and ambient noise imaging, which uses mathematical tools from probability, partial differential equations and asymptotic analysis, combined with the physics of wave propagation and modelling of imaging modalities.

Characterization of the effects of atmospheric lensing in SAR images

During the flight test of a Raytheon radar sensor in West Texas through 2007, Raytheon collected a wide variety of SAR images that showed evidence of atmospheric lensing. We have characterized the

Shape and motion estimate of LEO debris using light curves

We succeeded in determining a tri-axial ellipsoidal model of one LEO debris Cosmos 2082 rocket body, its rotational axis direction in the celestial sphere, a compositional parameter, its rotation

Small space object imaging : LDRD final report.

We report the results of an LDRD effort to investigate new technologies for the identification of small-sized (mm to cm) debris in low-earth orbit. This small-yet-energetic debris presents a threat

Matched-Filter and Correlation-Based Imaging for Fast Moving Objects Using a Sparse Network of Receivers

This paper considers the problem of imaging a fast moving small object and proposes a system that consists of a powerful emitter and several passive receivers located on the ground.

Signal to Noise Ratio Analysis in Virtual Source Array Imaging

This work considers correlation-based imaging of a reflector located on one side of a passive array where the medium is homogeneous and the illumination by remote impulsive souring on the other side of the array by a stationary reflector.
