This paper presents an approach that allows the simultaneous radiation of fast chirp waveforms from multiple transmit antennas with perfect orthogonality. In contrast to conventional MIMO concepts, which typically consider one dimension of the signal, in this new approach the signals are multiplexed along the second dimension of the rangeDoppler-matrix. In addition to the theoretical discussion, proof-of-concept measurements with an automotive radar prototype are shown.
