SCAIM Seminar: Margaret Cheney

Abstract

This talk explores the spatial, temporal, and spectral attributes of radar data and the associated target information.  We see that existing signal-processing approaches combine these attributes, two at a time, to form images.

The question of combining all three attributes arises in the problem of using fixed, distributed sensors to image multiple moving targets.  This talk explains how a comprehensive theory can be developed that incorporates sensor positions and the (possibly different) waveforms transmitted by the various transmitters.   The theory leads to a formula for producing an image and a formula for the imaging point-spread function.   Included are plots of the point-spread function for various geometries and waveforms.
