Detection in heterogeneous clutter by filter output prediction

This paper introduces an innovative method for ground moving target indication with a multichannel air or spaceborne radar. It is based on comparing the power of the filtered receive signal with a predicted power level. This prediction is found using data from the range line under test only. No potentially misleading prior magnitude information is employed. Thus, the false alarm probability is stabilized and the method is especially suited for rapidly varying heterogeneous terrain.
