分析了合成孔径雷达(SAR) 的图像信号模型, 阐述了应用数据外推方法提高分辨率的可行性.
提出一种最小方差谱估计和最小加权范数约束结合的非参数类数据外推方法. 该方法外推SAR …

We present a frequency estimation method based on a sparse representation of irregular
samples with an overcomplete basis. We enforce sparsity by imposing penalties based on …

The increase in space debris can seriously threaten regular activities in the Low Earth Orbit
(LEO) environment. Therefore, it is necessary to develop robust, efficient and reliable …

Для цитирования: Разработка и применение графа азимутальной обработки

A novel technique is proposed for ultra-wideband imagery of space objects from distributed
multi-band radar data. The complex exponential (CE) model is used for representation of …

The problem of sparse signal recovery can be formulated as a problem of finding a sparse
solution X∈[special characters omitted] to an underdetermined system of equations [special …

A generalized Papoulis-Gerchberg (PG) algorithm for signal extrapolation based on the
wavelet representation has been recently proposed by Xia, Kuo and Zhang. In this research …

Methods for best basis selection (BBS) can be used to address the problem of harmonic
retrieval using a large basis of harmonically related complex sinusoids with an iterative …

A series of algorithms are described in order of increasing complexity and improved
performance. The original scheme of Papoulis and Chamzas (1979) serves as a model for …
