MIMO radar transmit array fed by a 1 × M passive chaotic cavity

Abstract : —It is well known that MIMO radar waveforms should be orthogonal to probe simultaneously the MIMO channel matrix H. This method is not easily implementable since it requires as much transmitter chains as antennas. Herein, a compressive technique is introduced to measure the channel information avoiding multiple waveforms generation. This technique is thus based on the generation of a single waveform to probe the channel by the mean of a passive chaotic component connected to the transmit array. Mathematical formulations are presented considering a device with uncorrelated transfer functions allowing the transmission of orthogonal waveforms. Simulation and experimental results are presented to highlight the advantages of such a technique.
