Multi-Channel Deconvolution for Forward-Looking Phase Array Radar Imaging

Abstract: The cross-range resolution of forward-looking phase array radar (PAR) is limited by the effective antenna beamwidth since the azimuth echo is the convolution of antenna pattern and targets’ backscattering coefficients. Therefore, deconvolution algorithms are proposed to improve the imaging resolution under the limited antenna beamwidth. However, as a typical inverse problem, deconvolu...

Bayesian Analysis of Linear Phased-array Radar

A number of methods have been developed to analyze the response of the linear phased array radar. These perform remarkably well when the number of sources is known, but in cases where a determination of this number is required, problems are often encountered. These problems can be resolved by a Bayesian approach. Here, a linear phased-array consisting of equally spaced elements is considered. A...

Array error calibration methods in downward-looking linear-array three-dimensional synthetic aperture radar

In order to achieve high-precision three-dimensional (3-D) imaging with an airborne downward-looking linear-array 3-D synthetic aperture radar (LA-3D-SAR), a uniform virtual antenna array can be obtained by aperture synthesis of the cross-track sparse multiple-inputmultiple-output array. However, the actual 3-D imaging quality is unavoidably degraded by array errors such as the multichannel amp...

Statistical Analysis of Radar Rainfall Error Propagation

The prediction uncertainty of a hydrologic model is closely related to model formulation and the uncertainties in model parameters and inputs. Currently, the foremost challenges concern not only whether hydrologic model outputs match observations, but also whether or not model predictions are meaningful and useful in the contexts of land use and climate change. The latter is difficult to determ...
