Abstract

Als Radartarnmaterial zur Verringerung des Radar-Rück­ streuquerschnitts eines Zielobjekts wird eine dünne Schicht oder Folie aus dielektrischem Material mit einer Vielzahl einzelner Antennenelemente (A) des Typs minimal­ streuender Antennen, vorzugsweise Ringantennen vorge­ schlagen, die rein reaktiv (Z) belastet sind. As radar camouflage material to reduce the radar rear scattered cross section of a target becomes a thin one Layer or foil of dielectric material with a Large number of individual antenna elements (A) of the minimal type scattering antennas, preferably ring antennas beat that are purely reactive (Z).
