Abstract:

A space-time clutter block canceller (STCBC) applied to the MIMO radar is proposed.The equivalence between the spatial domain and the temporal domain information is exploited to make a cancellation between the clutter blocks by designing a coefficient matrix.The performance of following space-time adaptive processing (STAP) algorithms can also be enhanced.The simulation experiment shows that this method can effectively suppress the clutter in side-looking and non-side-looking airborne MIMO radar,and can further improve the moving target detection capability.
