Coherent ultrawideband random noise radar systems

recent developments in Doppler estimation and SAR/ISAR imaging

Research output: Contribution to journalArticle

Abstract

The University of Nebraska-Lincoln has developed and field tested a coherent ultrawideband polarimetric random noise radar system that shows great promise in its ability to covertly estimate Doppler and image targets and terrain features. The system uses the technique of heterodyne correlation processing to preserve phase coherence, an essential ingredient in Doppler estimation and imaging applications. Prior work has been presented at past SPIE conferences on this topic. Some recent exciting developments have taken place that further underscore the utility of this system in operational scenarios. These include the accurate estimation of Doppler velocities, and achievement of theoretical slant-range and cross-range resolutions in SAR imaging in an outdoor environment at approximately 200 meters range using a photonic delay line provided by SPAWAR. The experimental results are also supported by theoretical modeling and more controlled experimentation. This paper will summarize recent developments and discuss future research directions in this area. Companion poster papers by our group will provide more detailed information on the results.
