CS-MIMO radars for through-the-wall imaging with simultaneous transmission
Through-the-wall radars (TWR) are indispensable for situational awareness in a wide range of civilian and military applications. Multi-input multi-output (MIMO) TWR exploit spatial diversity to improve the target detection performance of TWR in indoor environments. MIMO TWR combined with compressive sensing (CS) enable good performance while reducing the number of samples needed for target estimation and the data acquisition time. In previous MIMO TWR approaches, all antennas transmit the same waveforms in a time-division access fashion. This work presents a CS-MIMO TWR approach, in which the TX antennas transmit simultaneously different waveforms, thus allowing for further reduction of acquisition time.
