MOTION COMPENSATION ALGORITHM FOR SINGLE TRACK FMCW CSAR BY PARAMETRIC SPARSE REPRESENTATION

Sparse and Independent Representation Parametric Mo

Recently methods for obtaining sparse representations of a signal using overcomplete dictionaries of waveforms have been studied, often motivated by the way the brain seems to process certain sensory signals. Algorithms have been developed using either a specific criterion to choose the waveforms occurring in the representation from a fixed dictionary, or to construct them as part of the method...

Low complexity motion estimation algorithm by multiresolution search for long-term memory motion compensation

We propose a new low complexity motion estimation (ME) algorithm using multiresolution motion search for long term memory motion compensation (LTMC, [1]). While multiresolution motion search has been used for standard single-frame motion compensation, here we introduce several novel techniques to exploit it efficiently in the context of LTMC. The proposed algorithm computes a coarse motion vect...

FMCW sparse array imaging and restoration for microwave gauging

The application of imaging radar to microwave level gauging represents a prospect of increasing the reliability of target detection. The aperture size of the used sensor determines the underlying azimuthal resolution. In consequence, when FMCW-based multistatic radar (FMCW: frequency modulated continuous wave) is used, the number of antennas dictates this essential property of an imaging system...

Registration-based Compensation using Sparse Representation in Conformal-array STAP

Space-time adaptive processing (STAP) is a well-suited technique to detect slow-moving targets in the presence of a clutter-spreading environment. When considering the STAP system deployed with conformal radar array (CFA), the training data is range-dependent, which results in poor detection performance of traditional statistical-based algorithms. Current registration-based compensation (RBC) i...
