A PARAFAC-based technique for detection and localization of multiple targets in a MIMO radar system

In this paper, we show that the problem of detection and localization of multiple targets in a bistatic MIMO radar system can be solved by parallel factor (PARAFAC) analysis. Our method is deterministic and fully capitalizes on the strong algebraic structure of the received data, where the radar cross section (RCS) fluctuation is not regarded as a nuisance parameter but rather as a source of time diversity. Simulation results show that our technique outperforms existing beamforming-based radar imaging methods at a lower complexity.
