The Radar Cross Section (RCS) of moving targets varies dramatically with aspect or time. The accuracy of simulated dynamic RCS is very important for radar system simulation. A novel approach to simulate the dynamic RCS of aircraft is proposed in this paper. Firstly, the electromagnetic (EM) model of aircraft is built and the all-space monostatic RCS database calculated. Secondly, the aspect angles (azimuth and elevation) in target coordinate system are calculated from ∞ight path by coordinate transformation. Then dynamic RCS is obtained based on database and aspect angles by linear interpolation method. Account for the in∞uence results from aircraft vibration in target motion, we use a white Gaussian distributed random series to modify the simulated results. The statistical characteristics of three kinds of dynamic RCS values are investigated, and the desirable agreement of results between modiflcation and measurement shows the applicability of this simulation approach.
