Claim 0:
1. An apparatus comprising:
a radar circuit with signal transmission circuitry to transmit radar signals and with signal reception circuitry to receive, in response, reflection signals as reflections from objects; and
computer processing circuitry to process data corresponding to the reflection signals in a multi-input multi-output (MIMO) virtual array characterized by having at least three embedded uniform sparse linear arrays, each of the at least three embedded uniform sparse linear arrays 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.
