摘要

摘要本文研究了喇叭天线辐射圆形介质物体的周期脉冲衍射,并进行了实验验证。汉明权函数(汉明窗)形式的脉冲频谱占据38 ~ 52 GHz频段。采用辅助源法解决了这一问题,并得到了计算机仿真结果。该方法的根本优点是消除了由各散射体的边界条件求得的积分方程在求解过程中的奇异性问题。并与实验数据进行了比较,仿真结果与实验结果吻合较好。利用散射脉冲回波分析确定目标电尺寸的正确性验证了该方法的有效性。结果表明,数值分析与实验分析的偏差小于3%。

Pulse diffraction by a circular dielectric cylinder
Abstract In this article, the periodic pulse diffraction from the circular dielectric object radiated by the horn antenna is investigated and experimental verification is provided. The pulse spectrum with Hamming weight function (Hamming window) form occupies the frequency band of 38 – 52 GHz. The problem is solved using the Method of Auxiliary Sources, and the results of the computer simulation are obtained. The fundamental advantage of the method is to eliminate the singularity problem during the solution of the integral equation obtained by boundary conditions on each scatterer. The comparison is done with the experimental data, which shows good agreement between the simulation outcomes and the experimental ones. The correctness of the determination of the electric size of the object by the analysis of the scattered pulse echo serves as the verification of the approach. The outcomes reveal that less than a 3% deviation is observed between numerical and experimental analysis.
