1. A method for completing measurements for a uniform linear array from measurements from a sparse linear array in a vehicle comprising:
receiving a first set of measurements for a sparse linear array by a computing device of a vehicle from a MIMO radar associated with the vehicle;
generating a second set of measurements for a uniform linear array from the first set of measurements by the computing device of the vehicle, wherein the second set of measurements has a plurality of missing elements;
constructing a Hankel matrix using the uniform linear array by the computing device of the vehicle; and
using the Hankel matrix to determine values for the plurality of missing elements of the generated second set of measurements for the uniform linear array by the computing device of the vehicle.
