Experiment Design Regularization-Based Hardware/Software Codesign for Real-Time Enhanced Imaging in Uncertain Remote Sensing Environment
A new aggregated Hardware/Software (HW/SW) codesign approach to optimization of the digital signal processing techniques for enhanced imaging with real-world uncertain remote sensing (RS) data based on the concept of descriptive experiment design regularization (DEDR) is addressed. We consider the applications of the developed approach to typical single-look synthetic aperture radar (SAR) imagi...
متن کاملDynamic Experiment Design Regularization Approach to Adaptive Imaging with Array Radar/SAR Sensor Systems
We consider a problem of high-resolution array radar/SAR imaging formalized in terms of a nonlinear ill-posed inverse problem of nonparametric estimation of the power spatial spectrum pattern (SSP) of the random wavefield scattered from a remotely sensed scene observed through a kernel signal formation operator and contaminated with random Gaussian noise. First, the Sobolev-type solution space ...
متن کاملResolution-enhanced radar/SAR imaging: an experiment design framework combined with neural network-adapted variational analysis regularization
The convex optimization-based descriptive experiment design regularization (DEDR) method is aggregated with the neural network (NN)-adapted variational analysis (VA) approach for adaptive high-resolution sensing into a unified DEDR -VA-NN framework that puts in a single optimization frame high-resolution radar/SAR image formation in uncertain operational scenarios, adaptive despeckling and dyna...

The convex optimization-based descriptive experiment design regularization (DEDR) method is aggregated with the variational analysis (VA) approach for adaptive high-resolution sensing into a unified DEDR-VA framework that puts in a single optimization frame highresolution radar/SAR image formation in uncertain operational scenarios, adaptive despeckling and dynamic scene image enhancement for a...
متن کاملEnhanced, high resolution radar imaging based on robust regularization
We propose an enhanced image reconstruction method for spotlight-mode synthetic aperture radar (SAR). Our approach involves extension of feature preserving regularization techniques developed in other applications to the complex-valued SAR imaging problem. Compared to conventional image formation schemes, our approach offers increased resolvability of point-scatterers, enhancement of object sha...
