Patent attributes
A combined pulsed and FMCW AESA radar system is described. The radar system includes an AESA array of radiating elements, an array of TR modules, an RF combiner/splitter, a transmitter, a pulsed radar receiver and an FMCW radar receiver. Each TR module corresponds to a respective radiating element of the array of radiating elements. The transmitter is configured to transmit an excitation signal to excite selected or all radiating elements of the array of radiating elements via the TR modules. When the transmitter is in a pulsed radar mode, the pulsed radar receiver is configured to receive radar return signals via the RF combiner/splitter from radiating elements of the array of radiating elements via the TR modules. When the transmitter is in an FMCW radar mode, the FMCW radar receiver is configured to receive radar return signals from selected radiating elements of the array of radiating elements via the TR modules.
