The overview of the existing types of objects for discrete correlated interference creation is provided in the present paper. It discusses not only every object features and efficiency of angel clutter making, but considers the generally accepted classification of such clutter and terms for the modern radars' MTI systems suppression. At the same time the conventional objects for the correlative interference creation such as angle reflectors, Luneberg lenses and dipole scatterers as well as latest target simulators MALD-J are described in the paper. The legacy and the most widespread correlated interference suppression and moving targets selection devices and techniques are also referred to in the article and in addition their insufficient effectiveness are pointed for the filtering of the interference in same range discrete as the signal from real target. As an alternative the target selection technology based on the analysis of the scattered by these targets probing radiation and first of all its polarization characteristics is proposed. As an example confirming such approach implementation relevance the results of theoretical calculations of scattered electromagnetic radiation polarization degrees and scattering cross-sections for the simulating interfering objects prolate spheroids with two different complex refraction indexes are provided.
