瞬態(tài)電磁場在目標(biāo)識別中的新應(yīng)用
NEW UTILIZATION OF TRANSIENT EM-FIELDS FOR TARGET DISCRIMINATION
-
摘要: 本文論述了瞬態(tài)電磁場用于目標(biāo)識別的一種新方法,給出了激勵目標(biāo)的單模散射場的基本理論及其數(shù)學(xué)推導(dǎo)過程。把這一理論用于線性目標(biāo)和導(dǎo)電球體,已獲得了較為滿意的結(jié)果,給出了計算目標(biāo)沖擊響應(yīng)得到的有用的結(jié)論。最后提出了一個實際可行的,在時域中測試目標(biāo)沖擊響應(yīng)的方案。實驗證明這一方案是可行的。

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. -
