英文摘要: In this paper, we propose a range reconstruction method for a frequency-band shared multipleinput multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) radar with sufficient cyclic prefix (CP) by using real orthogonal designs. Compared with the application of complex orthogonal designs in our previous work, the application of real orthogonal designs can significantly reduce the number of the all-zero-valued pulses in a coherent processing interval (CPI) for each transmitter and increase the efficiency of radar transmitters. Meanwhile, it still maintains the advantages of full spatial diversity without inter-range-cell interference (IRCI). We also apply the rate-1 real orthogonal designs for different numbers of transmitters and pulses for range reconstruction without...
