Abstract
A method and device for bandpass filter demodulation for FM-CW systems which includes providing a FM-CW signal to an input of a bandpass demodulator, amplifying the FM-CW signal, timing the bandpass demodulator at an integer multiple of the FM-CW signal frequency, and simultaneously demodulating/filtering the FM-CW signal to produce a signal in baseband containing suppressed carrier-Doppler sideband information from the FM-CW signal. The demodulating/filtering functions are performed in an appropriately biased and clocked switched capacitive filter.
