S-Band FMCW Radar with Range Gate




This video demonstrates the analog range gate in action.  The analog range gate was key to imaging through concrete walls using this system:

It facilitates the use of long duration waveforms for through-wall imaging while also reducing clock rate and dynamic range requirements of the radar's ADC.
