Analysis on Ultra-wideband Scattering Characteristics of Complex Missile with Empennages

摘要

摘要: 为了满足对复杂导弹测量和检测的需要，该文建立了具有尾翼的复杂导弹模型，研究在极窄脉冲照射条件下该导弹目标散射特性。利用时域有限差分(Finite-Difference Time Domain, FDTD)法计算该导弹模型的瞬时散射回波，分析远场电磁波不同入射条件下导弹散射回波特性及近场不同转角条件下导弹瞬时散射回波特性。通过对该导弹瞬时散射回波特性分析，得出了目标散射中心的成因及散射波形特点，在雷达应用领域具有一定的理论参考价值。

Abstract: In order to meet the requirement for measurement and detection of complex missile targets, a complex missile model with empennages is established and its scattering characteristics are studied under the conditions of the missile irradiated by extremely short pulse. Transient scattering echoes of the missile model are calculated using Finite-Difference Time Domain (FDTD) algorithm. The characteristics of the missile scattering echoes are analyzed at different incident angle conditions in far field and at different rotational angle of the missile in near field. These analyses on the scattering echo characteristics reveal the causes of the missile scattering centers and characteristics of scattering waveforms, which can provide theoretical reference in radar application.
