This paper describes a new non-homogeneous clutter and interference mitigation method for forward-looking airborne early warning radar with arbitrary linear array configuration.The approach is performed in three stages

i.e.the minimal mean square space-time spectral estimation with iterative processing which using only a single range bin data

the clutter and jammer ridge reconstruction based on image feature extraction

moving target detection with subspace projection.An important feature of the proposed method is its ability to extract requisite implementation information from the data itself without sacrificing space-time aperture.A preliminary result against an airborne simulation data demonstrates the effectiveness of the proposed method.
