Abstract:
In consideration of the influence of moving target to the target radar cross section(RCS), an exact RCS modeling method of moving target based on the measured data is proposed in this paper. Firstly, we use laser scanning method to build the precise geometric model of the real target. Secondly, we extract the parameters of the target motion characteristics in the actual flight and use the attitude angle in simulated program. Finally, we develop integration software to calculate the electromagnetic scattering, and eliminate the effect of attitude angle variation to make simulated results coincide with actual situation. The results show that it can obtain high accuracy results of aircraft dynamic RCS quickly, and have stronger applicability in engineering.
