Bistatic Synthetic Aperture Radar Imaging of Moving Targets Using Ultra-Narrowband Continuous Waveforms
We consider a synthetic aperture radar (SAR) system that uses ultra-narrowband continuous waveforms (CWs) as an illumination source. Such a system has many practical advantages, such as the use of relatively simple low-cost and low-power transmitters, and in some cases, using the transmitters of opportunity, such as television and radio stations. Additionally, ultra-narrowband CW signals are su...
متن کاملSynthetic Aperture Radar Imaging of Moving Targets Using Ultra-Narrowband Continuous Waveforms
We present a novel method of imaging multiple moving targets using a SAR system transmitting ultra-narrowband continuous waveforms. Our method comprises of a new forward model that relates the velocity as well as re ectivity information at each location to a correlated received signal; and a novel image formation method based on ltered-backprojection and image-contrast optimization. The method ...
متن کاملParameter estimation and imaging of moving targets in bistatic synthetic aperture radar
In high-resolution bistatic synthetic aperture radar (SAR) systems, parameter estimation is essential to moving target imaging quality. However, precise parameters are difficult to obtain without priori information due to the relative along-track and across-track velocities between the moving target and platforms that change with time. A parameter estimation and imaging approach for moving targ...
متن کاملDoppler Synthetic Aperture Radar Interferometry: A Novel SAR Interferometry for Height Mapping using Ultra-Narrowband Waveforms
This paper introduces a new and novel radar interferometry based on Doppler synthetic aperture radar (Doppler-SAR) paradigm. Conventional SAR interferometry relies on wideband transmitted waveforms to obtain high range resolution. Topography of a surface is directly related to the range difference between two antennas configured at different positions. Doppler-SAR is a novel imaging modality th...
