New Approaches to Direction-of-Arrival Estimation With sensor arrays in Unknown Nonuniform Noise
收藏 引用
IEEE sensorS JOURNAL 2016年 第24期16卷 8982-8989页
作者: Liao, Bin Huang, Lei Guo, Chongtao So, Hing Cheung Shenzhen Univ Coll Informat Engn Shenzhen 518060 Peoples R China City Univ Hong Kong Dept Elect Engn Hong Kong Hong Kong Peoples R China
It is known that classical subspace-based direction-of-arrival (DOA) estimation algorithms are not straightforwardly applicable to scenarios with unknown spatially nonuniform noise. Among the state-of-the-art solution... 详细信息

Blind Gain and Phase Calibration via Sparse Spectral Methods
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2019年 第5期65卷 3097-3123页
作者: Li, Yanjun Lee, Kiryung Bresler, Yoram Univ Illinois Urbana IL 61801 USA Ohio State Univ Dept Elect & Comp Engn Columbus OH 43210 USA Univ Illinois Coordinated Sci Lab Urbana IL 61801 USA Univ Illinois Dept Elect & Comp Engn Urbana IL 61801 USA
Blind gain and phase calibration (BGPC) is a bilinear inverse problem involving the determination of unknown gains and phases of the sensing system, and the unknown signal, jointly. BGPC arises in numerous application... 详细信息

ON THE SENSITIVITY OF THE ESPRIT ALGORITHM TO NONIDENTICAL SUBarrayS
收藏 引用
SADHANA-ACADEMY PROCEEDINGS IN ENGINEERING SCIENCES 1990年 第3期15卷 197-212页
作者: SWINDLEHURST, A KAILATH, T Department of Electrical and Computer Engineering Brigham Young University Provo USA Information Systems Laboratory Stanford University Stanford USA
ESPRIT (estimation of signal parameters via rotational invariance techniques) is a recently introduced algorithm for narrowband direction-of-arrival (DOA) estimation. Its principal advantage is that the DOA parameter ... 详细信息

Effect of Approximate Planar Wavefront on Far-Field Direction Finding
收藏 引用
IEEE COMMUNICATIONS LETTERS 2022年 第3期26卷 657-661页
作者: He, Jin Shu, Ting Shanghai Jiao Tong Univ Sch Elect Informat & Elect Engn Shanghai Key Lab Intelligent Sensing & Recognit Shanghai 200240 Peoples R China
Existing sensor array direction-finding algorithms in the open literature simplify the far-field source wavefront as exactly planar in order to facilitate the algorithmic development. In fact, since the wavefront of a... 详细信息

11th IEEE Workshop on Statistical Signal processing (SSP 2001)
作者: Boonstra, AJ van der Veen, AJ Netherlands Fdn Res Astron ASTRON NL-7991 PD Dwingeloo Netherlands
In radio telescope arrays, the complex receiver gains and sensor noise powers are initially unknown and have to be calibrated. Gain calibration enhances the quality of astronomical sky images and moreover, improve the... 详细信息
