Claim 11:
12. The MIMO radar apparatus of claim 11, wherein the receiver circuitry is further configured to:
perform a first range fast Fourier transform (FFT) of first receive signals corresponding to a sequence of first receive time intervals to generate a first range signal associated with the first subset of transmit channels;
perform a first Doppler FFT of the first range signal to generate a first Doppler signal associated with the first subset of transmit channels;
separate range-Doppler bins associated with different transmit channels of the first subset of transmit channels based on comparing the first Doppler signal to the first predefined code division multiplexing scheme to obtain a first quantity of range-Doppler-maps corresponding to a quantity of transmit channels in the first subset of transmit channels;
perform a second range FFT of second receive signals corresponding to a sequence of second receive time intervals to generate a second range signal associated with the second subset of transmit channels;
perform a second Doppler FFT of the second range signal to generate a second Doppler signal associated with the second subset of transmit channels; and
separate range-Doppler bins associated with different transmit channels of the second subset of transmit channels based on comparing the second Doppler signal to the second predefined code division multiplexing scheme to obtain a second quantity of range-Doppler-maps corresponding to a quantity of transmit channels in the second subset of transmit channels.
