Abstract :
Moving target indication (MTI) is demonstrated for general antenna arrays, especially sparse 3D arrays. The framework for space-time adaptive processing (STAP) is generalized to include frequency (fast-time) data and array elements offset in cross track dimensions. The degrees of freedom (rank) needed to represent clutter are derived for general systems. The clutter rank compared to the number of independent samples collected by a radar determine whether MTI is achievable. The optimum detector and the minimum norm eigen canceler (MNE) are implemented through simulation to demonstrate effective clutter cancellation
