Abstract :
High transmit/receive (Tx/Rx) isolation of phased-array systems on board future US Navy ships is critical to preserving the performance of these systems. The advanced multifunction radio frequency (AMRFC) Testbed is a one-of-a-kind phased-array system that was evaluated to determine the level of Tx/Rx isolation for certain scan angles. The effective-radiated power (ERP) of the AMRFC Tx array was also evaluated to verify the emission characteristics under certain conditions. The preliminary results of evaluating the Tx/Rx isolation and ERP are discussed in this paper.
