2-D Coherence Factor for Sidelobe and Ghost Suppressions in Radar Imaging [PDF]
, 1956 The coherence factor (CF) is defined as the ratio of coherent power to incoherent power received by the radar aperture. The incoherent power is computed by the multi-antenna receiver based on only the spatial variable.
