WebFigure 8, for an FMCW radar with NTX = 2, alternate time slots are dedicated to TX1 and TX2. TDM-MIMO is the most simple way to separate signals from the multiple TX antennas and is therefore widely used. In a typical processing scheme for TDM-MIMO FMCW radar, the 2D-FFT (range-Doppler FFT[5]) is performed for each TX-RX pair. WebJonghun Lee.
