Claim 10:
11. 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 identifying one or more correlated points from one or more pairs of transmitters and receivers in at least one of the first and second sets of virtual array elements and applying a global phase correction for the one or more pairs of transmitters and receivers in the second set of virtual array elements using the one or more correlated points to compensate for temporal or spatial mismatches between the first and second sets of virtual array elements.
