Abstract:

Aiming at the excessive clutte's DOFs (degrees of freedom) and huge demand for training samples of 3D-STAP,a three  dimensional  space- time open-loop  clutter  block  canceller (3D-STCBC) is proposed. First, the vector-matrix model of the three dimensional clutter is constructed with the a priori knowledge. Then the equivalence between the spatial domain and the temporal domain is exploited to design a coefficient matrix to make a cancellation between the clutter blocks. The experiment shows that this method can effectively suppress the clutter even with small samples and dramatically lower the clutter's DOFs.

Key words: airborne radar, three dimensional space-time adaptive processing (3D-STAP), clutter suppression
