Claim 12:
13. For use in a radar circuit with signal transmission circuitry, a method comprising:
transmitting radar signals and, in response, receiving reflection signals as reflections from objects; and
providing a multi-input multi-output (MIMO) virtual array, via computer processing circuitry, characterized by having at least three embedded sparse linear arrays, each of the at least three embedded sparse linear arrays being uniform and each being associated with a unique antenna-element spacing from among a set of unique co-prime antenna-element spacings, wherein spacing values of the at least three embedded sparse linear arrays are co-prime, pairwise, and the at least three embedded sparse linear arrays form an array of sparse aperture of a size corresponding to a lowest common multiple of the spacing values.
