摘要： A Simultaneous Transmit and Receive (STaR) system utilizing high power transmitters and high sensitivity receivers in conjunction with one or more signal polarizers to maintain far-field polarization efficiency for both transmission and reception of same (or similar) frequency content at the same time. This STaR system maintains far-field polarization efficiency to remote target(s) while simultaneously introducing a near-field polarization mismatch between the transmission and receiver subsystems for higher isolation and reduced coupling.
