MULTI-FUNCTION SHARED APERTURE ARRAY

摘要

A multi-function radio frequency (RF) system may include a shared phased array antenna subsystem for transmitting and receiving radar signals and communications signals. The system may also include an integrated electronics package configured for controlling operation of the shared phased array antenna subsystem. The integrated electronics package may include a modulator/demodulator subsystem. The modulator/demodulator subsystem may include a radar module that is selectively coupled to the shared phased array antenna subsystem for transmitting and receiving radar signals. The radar module is configured to transmit and receive radar signals through the shared phased array antenna subsystem. The modulator/demodulator subsystem may also include a communications module that is selectively coupled to the shared phased array antenna subsystem for transmitting and receiving communications signals. The communications module is configured to transmit and receive communications signals through the shared phased array antenna subsystem.
