Phase synchronization errors (PSEs) are practically inevitable for non-coherent MIMO radar with widely separated antennas, so in this paper a two-step generalized likelihood ratio test (2s-GLRT) algorithm to target detection under PSEs. The expectation-maximization (EM) algorithm and detection criterion are employed to estimate the channel parameter and acquire target detector respectively. Simulation...
In this paper, a new joint the direction of departures (DODs) and the direction of arrivals (DOAs) estimation method in the presence of unknown mutual coupling for bistatic multiple-input multiple-output radar (MIMO) radar is presented. By setting the auxiliary elements on the both sides of the transmit and arrays, the effect of mutual coupling can be eliminated and the standard MUSIC can be utilized...
The beampattern of MIMO (Multiple-input Multiple-output) radar is the product of transmitter and receiver beam pattern. Exploiting uniform linear array, the beampattern has no grating lode when a certain relation between the space of transmitter element and receiver element is met. Moreover, this kind of collocation takes on maximum virtual array aperture. Exploiting non-uniform linear array, the...
The Bi-static MIMO (multiple-input multiple-output) radar signal modal is established in this paper. And the proper coefficient of the MF (matcher filter) is chosen in order to keep the noise output has the same statistical property as the noise input. To make the computational complexity lower and the convergence speed faster, the signal subspace is used as a dimension-reducing matrix. A novel cost...
The ambiguity function of MIMO radar was presented from its own characteristics based on the ambiguity function of bistatic radar. Firstly, right-angle coordinate system was built as reference system for MIMO radar. Secondly, target coordinate and velocity were selected as variables of ambiguity function. Finally, the ambiguity function of MIMO radar was got, which was a combination of the ambiguity...
