Sparse Aperture Radar Imaging
Radar data collected from airplanes in real time is generally sparse except in very special cases. We demonstrate several tools and approaches to form images in some examples.
متن کاملCoherent interferometric imaging for synthetic aperture radar
This paper shows that the coherent interferometric imaging strategy originally proposed in the context of passive or active arrays of antennas can be implemented for synthetic aperture radar, in which a single antenna is used as an emitter and as a receiver at successive positions along a trajectory. The idea is to backpropagate the cross correlations of the recorded signals over selected frequ...
متن کاملSynthetic aperture radar imaging exploiting multiple scattering
In this paper, we consider an imaging scenario, where a bi-static synthetic aperture radar (SAR) system is used in a multiple scattering environment. We consider a ray-theoretic approximation to the Green function to model a multiple scattering environment. This allows us to incorporate the multiple paths followed by the transmitted signal, thereby providing different views of the object to be ...
متن کاملSynthetic Aperture Radar Imaging of Internal Waves
Over the past 10 years, synthetic aperture radars (SAR) have frequently detected pronounced signatures of nonlinear, coastal internal waves 1-6 that are produced by the interaction of short-wavelength surface waves with internal wave-induced surface currents. A qualitative representation of the signature generation process is shown in Fig. 1 for a group of nonlinear internal waves. At the leadi...
متن کاملSynthetic Aperture Radar Imaging Simulated in MATLAB
Synthetic Aperture Radar Imaging Simulated in MATLAB Matthew Schlutz This thesis further develops a method from ongoing thesis projects with the goal of generating images using synthetic aperture radar (SAR) simulations coded in MATLAB. The project is supervised by Dr. John Saghri and sponsored by Raytheon Space and Airborne Systems. SAR is a type of imaging radar in which the relative movement...
