Half Inverted Nested Arrays with Large Hole-Free Fourth-Order Difference Co-Arrays
ICASSP 2022accepted
Sparse arrays with fourth-order cumulant processing can identify up to $\mathcal{O}\left( {{N^4}} \right)$ source directions with only N physical sensors. To achieve this property, the fourth-order difference co-array is preferable to own a contiguous segment with no holes. However, existing sparse…
