Abstract: The discrimination problem of active decoy and radar target was studied based on a high resolution and timesharing polarization measurement radar system. The polarization characteristics of active decoy of any elliptic polarized antenna were analyzed, ana the analytic expression of its instantaneous polarization projection vector (IPPV) was given. The IPPV fluctuation characteristics of scattering echo from radar target were also dis?cussed .The concept and definition of IPPV horizontal fluctuation degree, IPPV vertical fluctuation degree and partial fluctuation degree, whicn can be used to characterize the different polarization characteristics of radar tar?get and active decoy, were then presented. The polarization discrimination algorithm of active decoy and radar target was established. The feasibility and validity of identification proposal are verified by actual data and com?puter simulation.
