Abstract
AbstractIn radar systems with a common Tx/Rx antenna, duplexers are used to separate Tx/Rx signals during operation. Especially for high-power radar systems, Tx/Rx duplexers are key components, affecting the overall system performance. This letter presents a novel Tx/Rx duplexer concept, suitable for circular full-polarimetric radar operation with multi-kW transmission power and broad bandwidth. The concept allows to push the reconnaissance capability of future broadband high-power radar sensors for space observation.
