Performance Prediction of FDA-MIMO Radar Detector

Due to the complex shape of the target, the radar cross-section (RCS) scintillations of the target will affect the radar detection performance. Therefore, a signal model for frequency diverse array (FDA) multiple-input and multiple-output (MIMO) radar based on the distributed source model is constructed in this paper, which takes advantage of spatial diversity. Furthermore, the detection performance of the FDA-MIMO radar multi-pulse detector is analyzed for targets conform to Swerling I and Swerling II model. Numerical results show its advantages over the MIMO radar detector at low signal-to-noise ratio (SNR).
