Phase Retrieval with One or Two Diffraction Patterns by Alternating Projection with Null Initialization
Pengwen Chen, Albert Fannjiang, Gi-Ren Liu
Alternating projection (AP) of various forms, including the Parallel AP (PAP), Real-constrained AP (RAP) and the Serial AP (SAP), are proposed to solve phase retrieval with at most…
Fourier-Domain Fixed Point Algorithms with Coded Diffraction Patterns
Albert Fannjiang
Fourier-domain Difference Map (FDM) for phase retrieval with two oversampled coded diffraction patterns are proposed. FDM is a 3-parameter family of fixed point algorithms includin…
Compressive Radar with Off-Grid Targets: A Perturbation Approach
Albert Fannjiang, Hsiao-Chieh Tseng
Compressed sensing (CS) schemes are proposed for monostatic as well as synthetic aperture radar (SAR) imaging with chirped signals and Ultra-Narrowband (UNB) continuous waveforms.…
Compressed Remote Sensing of Sparse Objects
Albert Fannjiang, Pengchong Yan, Thomas Strohmer
The linear inverse source and scattering problems are studied from the perspective of compressed sensing, in particular the idea that sufficient incoherence and sparsity guarantee…
