The -model for Random Graphs --- Regression, Cramér-Rao Bounds, and Hypothesis Testing
Johan Wahlström, Isaac Skog, Patricio S. La Rosa +2
We develop a maximum-likelihood based method for regression in a setting where the dependent variable is a random graph and covariates are available on a graph-level. The model gen…
Coarrays, MUSIC, and the Cramér Rao Bound
Mianzhi Wang, Arye Nehorai
Sparse linear arrays, such as co-prime arrays and nested arrays, have the attractive capability of providing enhanced degrees of freedom. By exploiting the coarray structure, an au…
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…
