1. A method of performing beamforming, comprising:

  • applying matched filtering to each of a plurality of received signals to generate a virtual antenna array output for a multiple-input multiple-output (MIMO) radar system;

    performing, using the virtual antenna array output, delay-and-sum (DAS) beamforming to generate an initial power spectrum estimation associated with the plurality of received signals; and

    generating beamforming data based on an iterative adaptive approach (IAA) that includes a number of iterations using the initial power spectrum estimation as an initial power estimation, and iteratively updating and evaluating the initial power estimation in one of a plurality of different beam directions.
