摘要

A hybrid space-time adaptive processing (STAP) approach of the direct data domain (DDD) algorithm and adaptive localised domain transformation is proposed for discrete interference suppression in non-homogeneous clutter which is inevitable in actual airborne radar applications. In the proposed method, the adaptive localised domain transformation matrix is firstly formed by the DDD weighting vectors in angle-Doppler directions to suppress discrete interference. Afterwards, the adaptive localised domain transformation matrix is applied to the conventional STAP method to suppress the residual clutter. The proposed method is verified based on the actual airborne radar data.
