摘要： A device and method is disclosed for a hybrid multi-mode airborne and rotary wing radar Electronically Scanned Antenna (ESA). Pulsed Radio Frequency Integrated Circuit (RFIC) Transmit and Receive Modules (TRM) are nested with Frequency Modulated Continuous Wave (FMCW) transmit elements within the aperture of an ESA. FMCW elements only transmit while the pulsed TRM receive both the pulsed return and the FMCW return. During the hybrid configuration, both the pulsed and FMCW performance is limited to less than the full ESA aperture. In an alternate configuration, individual TRM are configured for transmit and receive of both FMCW and pulsed signals are coupled within the aperture of the ESA. The individual elements offer full aperture performance in both pulsed and FMCW operation. A diplexer controls channel deconfliction between the pulsed and the FMCW transmissions/receptions while a switching network directs the individual elements to hop between the pulsed and FMCW modes.
