Solving the discrimination problem by means of estimating the radar cross-section of a plasma sheath

The study deals with the problem of indicating a target as a decoy during radar tracking. We chose to investigate plasma-generating and heavy decoys moving along the atmospheric segments of their trajectories. We conducted simulations in the Fluent and ANSYS HFSS software packages. We suggest certain criteria for decoy discrimination and for making the decision to indicate the target as a decoy. We analysed whether it is possible to discriminate heavy and plasma-generating decoys during the atmospheric segment of their flight, using data obtained by X-ray radar stations
