摘要
A radar system includes a transmitter to transmit a sequence of pulses, a receiver to receive reflections of the transmitted pulses, and velocity detection circuitry to determine a velocity of an object in a path of the transmitted pulses based at least in part on the transmitted pulses and the reflected pulses. The transmitter includes a plurality of digital-to-analog converters (DACs) to generate the sequence of pulses in response to a clock signal. The receiver includes a plurality of analog-to-digital converters (ADCs) to sample the reflected pulses in response to the clock signal. Accordingly, the ADCs are locked in phase with the DACs.
