Abstract
The present disclosure relates to a multiple-input multiple-output (MIMO) radar system comprising an antenna comprising at least two sparse transmit arrays, each sparse transmit array comprising a plurality of antenna elements. The antenna elements of each sparse transmit arrays are at least partially overlapping with the antenna elements of the other sparse transmit arrays of the at least two sparse transmit arrays. Further, there is control circuitry connected to the antenna. The control circuitry is configured to transmit a signal having a waveform by means of each sparse transmit array, wherein the waveform of each signal is substantially orthogonal relative to a waveform of each other signal of each other sparse transmit arrays of the at least two sparse transmit arrays.
