Fourth-Order Hierarchical Array: A Novel Scheme for Sparse Array Design Based on Fourth-Order Difference Co-Array
Si Wang, Guoqiang Xiao
Conventional array designs based on circular fourth-order cumulant typically adopt a single expression form of the fourth-order difference co-array (FODCA), which limits the achiev…
A Novel Sparse Sum and Difference Co-Array With Low Redundancy and Enhanced DOF for Non-Circular Signals
Si Wang, Guoqiang Xiao
Array structures based on the sum and difference co-arrays provide more degrees of freedom (DOF). However, since the growth of DOF is limited by a single case of sum and difference…
A Novel Design Method for Seeking Sparse Linear Arrays With Low Redundancy and Enhanced DOF
Si Wang, Guoqiang Xiao
Sparse arrays with -sensors can provide up to degrees of freedom (DOF) by second-order cumulants. However, these sparse arrays like minimum-/low-redundancy arrays (MRAs…
FOGNA: An effective Sum-Difference Co-Array Design Based on Fourth-Order Cumulants
Si Wang, Guoqiang Xiao
Array structures based on the fourth-order difference co-array (FODCA) provide more degrees of freedom (DOF). However, since the growth of DOF is limited by a single case of fourth…
