Links referred to in the video are as follows. At first glance, this circuit appears to be to be a switching mixer. Rf from the antenna and the pair of quadrature squarewaves from the vfo system enter stage left, after which there's a filter and a transformer (essentially a balun to convert the unbalanced feed to a balanced input to the detector).
This project uses pic16f628a and ad9850 or ad9851. The bandwidth and the sweep time of the fmcw radar system are 150 mhz, and 270 us.
