瞬态电磁场在目标识别中的新应用
NEW UTILIZATION OF TRANSIENT EM-FIELDS FOR TARGET DISCRIMINATION
-
摘要: 本文论述了瞬态电磁场用于目标识别的一种新方法,给出了激励目标的单模散射场的基本理论及其数学推导过程。把这一理论用于线性目标和导电球体,已获得了较为满意的结果,给出了计算目标冲击响应得到的有用的结论。最后提出了一个实际可行的,在时域中测试目标冲击响应的方案。实验证明这一方案是可行的。

Abstract: A new scheme of target discrimination based on transient EM-fields is described in detail-in this paper. The fundamental theory and its mathematical deduction for getting scattering fields of single frequency of a excited target are given.We have got some more contented results, when this theory is used to linear target and conducting spheres. Several useful conclusions on calculating impulse response of targets are stated here. A practical and available scheme about measuring impulse response of a target in time domain is proposed Experimental results show that this new theory is useful. -
