Classification: CPC G  H | IPC G  H

Claim 15:
16. A method, comprising:
receiving radar data from a plurality of multiple input multiple output (MIMO) radar transceiver devices, each including one or more transmitters and one or more receivers disposed within a local oscillator domain; and
synthesizing a virtual antenna array with a distributed aperture using the radar data received from the plurality of MIMO radar transceiver devices, the virtual antenna array including a first set of virtual array elements defined by one or more pairs of transmitters and receivers from the same local oscillator domain and a second set of virtual array elements defined by one or more pairs of transmitters and receivers from different local oscillator domains;
wherein synthesizing the virtual antenna array with the distributed aperture includes aligning range profiles for the one or more pairs of transmitters and receivers in the second set of virtual array elements;
wherein aligning the range profiles for the one or more pairs of transmitters and receivers in the second set of virtual array elements is performed after performing a range transformation operation for the for the one or more pairs of transmitters and receivers in the second set of virtual array elements; and
wherein synthesizing the virtual antenna array with the distributed aperture includes performing transmitter code demodulation for the one or more pairs of transmitters and receivers in the second set of virtual array elements after aligning the range profiles for the one or more pairs of transmitters and receivers in the second set of virtual array elements.
