Patent ID: 8416121

Claim:
A frequency modulation continuous wave (FMCW) system comprising: a first memory receiving a clock signal and storing voltage digital values of I FMCW signals; a second memory receiving the clock signal and storing the voltage digital values of the Q FMCW signals; a first digital-to-analog converter (DAC) connected to the first memory and receiving the clock signal for converting the voltage digital values of the I FMCW signal to a first analog voltage; a second digital-to-analog converter (DAC) connected to the second memory and receiving the clock signal for converting the voltage digital values of the Q FMCW signal to a second analog voltage; an I low-pass filter connected to the first DAC smoothing the I FMCW signal; and a Q low-pass filter connected to the second DAC smoothing the Q FMCW signal.
