摘要
超宽带雷达具有高分辩能力,它探测到复杂目标时,目标总的电磁散射是多散射中心的合成,回波信号不同于普通的窄带雷达回波。文中分析了在超宽带信号照射下的目标散射特性,得到超宽带雷达的一般模型。对于超宽带线性调频信号,给出了目标回波的仿真结果。
Ultra wide band radar has high range resolution capability, when UWB signals interact with target, and the responses of target are composed of many separate scattering centers.In this paper, by analysis of the EM scattering properties illuminated by UWB signals, the conventional model is proposed.For UWB LFM radar signal, the simulations of scattering returns are presented.
