Abstract
A frequency-modulated continuous wave (FMCW) coded aperture radar (CAR) implemented on an integrated circuit (IC) to step through a range of frequencies in each sweep and a method of assembling the FMCW CAR implemented on an IC are described. The CAR implemented on the IC includes an antenna element to transmit or receive at a given time duration, a transmit channel to process a signal for transmission, the transmit channel including a transmit switch configured to change a state of a transmit phase shifter between two states based on a first code, and a receive channel to process a received signal, the receive channel including a receive switch configured to change a state of a receive phase shifter between two states based on a second code. A switch controller controls the first code and the second code and controls the first code to remain constant within the sweep.
