Switched-Element Direction Finding

Switched-Element Direction Finding

We introduce and evaluate the concept of switched-element direction finding. In a switched-element system, simultaneous data collection occurs on only a subset of the array's N elements at any given time. The data collection interval is divided into subintervals, and at each subinterval a multi...

Zusammenfassung:We introduce and evaluate the concept of switched-element direction finding. In a switched-element system, simultaneous data collection occurs on only a subset of the array's N elements at any given time. The data collection interval is divided into subintervals, and at each subinterval a multiplexer selects a different subset of M
