摘要

本文提出了一种在频域中分析任意形状PEC物体均匀运动时多普勒效应的新数值方法。利用跳帧技术和电积分方程法得到了散射场的频谱。在改变了PEC物体表面电流算子的阶数后，无需进行傅里叶变换即可得到静止坐标系中散射场相对于观测者的频谱，提高了该方法的效率。

The Numerical Analysis of the Doppler Effect of an Arbitrarily Shaped PEC Object in Uniform Motion

In the paper, a novel numerical method in the frequency domain of analyzing the Doppler effect of an arbitrarily shaped PEC object in uniform motion is proposed. The frame hopping technique and electric integral equation method are used to get the spectrum of the scattering field. After changing the order of operators on the surface current of the PEC object, no Fourier transformation need to be implemented to get the spectrum of the scattering field in the frame at rest with respect to the observer which makes the method efficient.
