doi:10.3969/j.issn.1000-1093.2012.01.007

Abstract

Abstract: The Multiple-Input Multiple-Output (MIMO) radar was proposed in recent years. Using MIMO radar to detect the location of multi-target, a lot of algorithms are failure when the multi-target echo signals are coherent. Concerning this problem, a localization algorithm of coherent multi-target is presented in bistatic MIMO radar. The algorithm constructs virtual array for both the transmit and receiver array to de-correlate the coherent multi-target echo signals, and then the location of multi-target can be obtained. The estimated parameters are automatically paired without additional paring computation. The proposed method avoids the array aperture loss and the performance of angle estimation is improved. Theoretical analysis and simulation results verify the effectiveness of this method.
