Abstract: Calculating planar arrays pattern is time-consuming in flight simulation whose frame synchronization time is within tens of milliseconds and this would cause removing frames. To resolve this problem, a graphic simulation method was presented to simulate planar arrays' pattern. Based on analyzing ideal patterns' graphic characteristics, a kernel function was constructed whose graphics could reflect all those pattern's characteristics. Then this kernel's graphics being used as a section plane were rotated in the spatial coordinates to match the ideal pattern. The simulation results show that this method can be rapidly calculated and the simulated pattern is highly true to the ideal pattern.
