Deterministic Cramer-Rao Bounds for Coherent Direction-of-Arrival Estimation: Rank Information Versus Coherence Structure
Weichao Zheng, Zai Yang
Direction-of-arrival (DOA) estimation is a fundamental problem in array signal processing, for which the Cramer-Rao bound (CRB) serves as a standard performance benchmark under bot…
Positivity of a Hadamard Product
Roger A. Horn, Shengxuan Luo, Hongwei Xu +1
A notable difference between the ordinary and Hadamard products is that the Hadamard product of two singular positive semidefinite matrices can be nonsingular, and one of the facto…
A Robust Super-resolution Gridless Imaging Framework for UAV-borne SAR Tomography
Silin Gao, Wenlong Wang, Muhan Wang +5
Synthetic aperture radar (SAR) tomography (TomoSAR) retrieves three-dimensional (3-D) information from multiple SAR images, effectively addresses the layover problem, and has becom…
Direction-of-Arrival Estimation for Constant Modulus Signals Using a Structured Matrix Recovery Technique
Xunmeng Wu, Zai Yang, Zhiqiang Wei +1
This paper addresses the problem of direction-of-arrival (DOA) estimation for constant modulus (CM) source signals using a uniform or sparse linear array. Existing methods typicall…
Multichannel Frequency Estimation in Challenging Scenarios via Structured Matrix Embedding and Recovery (StruMER)
Xunmeng Wu, Zai Yang, Zongben Xu
Multichannel frequency estimation with incomplete data and miscellaneous noises arises in array signal processing, modal analysis, wireless communications, and so on. In this paper…
