ABSTRACT:
A radar system array antenna includes plural elements. Each element is coupled to a port of a transmit-receive device. Digital data representing the characteristics of the radar signal is applied to a monolithic IC combination DAC/ADC, which converts the digital data into analog transmit signal. The analog transmit signal is applied to a monolithic microwave IC transceiver, which may be monolithic with the DAC/ADC. The transceiver upconverts the transmit signal. The upconverted transmit signal is applied to a transmit port of the transmit-receive device and transmitted. Receive RF signal is coupled from each antenna element through the transmit-receive device to a receive signal port of the transceiver. The transceiver downconverts the receive signal to produce received downconverted signal. The downconverted signal is coupled to the ADC part of the DAC/ADC, which converts to receive digital signal. Digital processing processes the receive digital signal to produce the return target information.
