16. A multi-station occupancy detector comprising:
an antenna array;
a radar transceiver coupled to the antenna array configured to provide transmit radar signals and to accept receive radar signals;
a memory having a set of azimuth-elevation-range parameter values for each of multiple stations configured to accommodate vehicle occupants; and
a controller configured to adjust relative phases of the transmit radar signals and analyze receive radar signals based at least in part on each set of azimuth-elevation-range parameter values, and to derive radar measurements indicating occupancy of each of the multiple stations based at least in part on the receive radar signals, wherein the multiple stations are non-line of sight with the radar transceiver, and
wherein the transmit radar signals and the receive radar signals are conveyed to a given station of the multiple stations via a corresponding reflector.
