Abstract: Due to the difficulty of field measurement of dynamic RCS of non-cooperative target, it is advantageous to use the simulation method to calculate the dynamic scattering. The all-round dynamic RCS of typical stealth aircraft was simulated based on all airspace static RCS database and aerodynamics. The attitude angles were modified by vibration model to make simulated results coincide with actual situation. In addition, Statistical modeling of dynamic RCS by c2 distribution,Log-normal distribution and Weibull distribution was investigated. The goodness-of-fit test results show log-normal distribution is a universal distribution to describe the dynamic RCS on different frequencies and polarizations. The results of this paper can provide a support for fast and accurate simulation of target's echo.
