AbstractThe paper considers the transition algorithm from incoherent models to partially coherent ones by the example of the problem of synthesizing a two‐dimensional partially coherent model of a distributed radar object by its five‐point and nine‐point incoherent models. The transition algorithm includes the analytical expressions which allow determining powers and correlation functions of emitting signals for both types of models. The result is confirmed by numerical modeling. The comparison of the precision reflection altimeter formation and correlation function of angular glint provided by equivalent incoherent and partially coherent models is carried out.
