“…Here, we give a revelatory method that all initial estimates of direction parameters are first computed by using the subspace-type algorithms proposed in [4][5][6][7][8], then, an initialization cycle of EM algorithm is carried out to calculate the initial estimates of remaining parameters, i.e., ζ and σ 2 . Till now, the initialization of the EM algorithm has been finished, and the E-M-step iteration will be repeated until some convergence criterion is achieved.…”

“…Furthermore, based on the placement geometry of transmit and receive antennas, the coherent MIMO radar can be distributed into two classes: One is bistatic MIMO radar; the other is monostatic MIMO radar. In this paper, we mainly discuss a bistatic MIMO radar architecture, whose direction finding (DF) is considered extensively [4][5][6][7][8]. Furthermore, the corresponding results derived here can be extended to monostatic MIMO radar [9][10][11] stemming from its virtual array.…”

“…On the other hand, considering the effect of mutual coupling in both the transmit array and receive array, the accuracy of angle estimation in [6][7][8][9][10] will be degraded remarkably. In order to solve this issue, the MUSIC-Like algorithm and ESPRIT-Like algorithm are presented to estimate the angle and mutual coupling for bistatic MIMO radar in [11,12], respectively. However, all the methods mentioned above are required to stack the received data into a special structure matrix, which ignore the multidimensional structure inherence in the received data.…”
