High Resolution Angle-Doppler Imaging for MTI Radar
IEEE Transactions on Aerospace and Electronic Systems, 2010 To reduce the need for training data or for accurate prior knowledge of the clutter statistics in space-time adaptive processing (STAP), we consider high resolution angle-Doppler imaging by processing each range bin of interest independently. Specifically, we use a weighted least-squares-based iterative adaptive approach (IAA) to form angle-Doppler ...

Reliable Orientation Estimation of Vehicles in High-Resolution Radar Images [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2016 With new generations of high-resolution imaging radars, the orientation of vehicles can be estimated without temporal filtering. This enables time-critical systems to respond even faster. Based on a large data set, this paper compares three generic algorithms for the orientation estimation of a vehicle.

High resolution radar imaging with small subarrays [PDF]
International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990 The autoregressive spectrum estimation technique is applied to far field array radar imaging. Due to the superresolution capability of this technique, high resolution radar images can be obtained with an incoherent combination of images formed by small subarrays. This solves the problem of phase calibration in large-array imaging systems.

High-Resolution, Quantitative Signal Subspace Imaging for Synthetic Aperture Radar
SIAM Journal on Imaging Sciences, 2022 We consider synthetic aperture radar imaging of a region containing point-like targets. Measurements are the set of frequency responses to scattering by the targets taken over a collection of individual spatial locations along the flight path making up the synthetic aperture.
