On Clutter Ranks of Frequency Diverse Radar Waveforms
Yimin Liu, Le Xiao, Xiqin Wang +1
Frequency diverse (FD) radar waveforms are attractive in radar research and practice. By combining two typical FD waveforms, the frequency diverse array (FDA) and the stepped-frequ…
The Random Frequency Diverse Array: A New Antenna Structure for Uncoupled Direction-Range Indication in Active Sensing
Yimin Liu, Hang Ruan, Lei Wang +1
In this paper, we propose a new type of array antenna, termed the Random Frequency Diverse Array (RFDA), for an uncoupled indication of target direction and range with low system c…
Direction of Arrival Estimation Using Co-prime Arrays: A Super Resolution Viewpoint
Zhao Tan, Yonina C. Eldar, Arye Nehorai
We consider the problem of direction of arrival (DOA) estimation using a newly proposed structure of non-uniform linear arrays, referred to as co-prime arrays, in this paper. By ex…
Joint Sparse Recovery Method for Compressed Sensing with Structured Dictionary Mismatches
Zhao Tan, Peng Yang, Arye Nehorai
In traditional compressed sensing theory, the dictionary matrix is given a priori, whereas in real applications this matrix suffers from random noise and fluctuations. In this pape…
Fixed point theory and semidefinite programming for computable performance analysis of block-sparsity recovery
Gongguo Tang, Arye Nehorai
In this paper, we employ fixed point theory and semidefinite programming to compute the performance bounds on convex block-sparsity recovery algorithms. As a prerequisite for optim…
Verifiable and computable performance analysis of sparsity recovery
Gongguo Tang, Arye Nehorai
In this paper, we develop verifiable and computable performance analysis of sparsity recovery. We define a family of goodness measures for arbitrary sensing matrices as a set of op…
