The fundament of two - dimension imaging for rotating target is discussed 讨论了旋转目标二维成像的基本原理。
Because of the equivalence of spotlight sar and rotating target imaging , the impsar pro jection reconstruction theory can be successfully used in spotlight impsar 本文利用点扩展函数推导了旋转目标成像在360和小角度时的分辨率解析表示。
With point spread function ( psf ) , the analytical expression of imaging resolution of the ultra - wideband ( uwb ) signal for both 360 ? and small angle rotating target are given 不同于其它uwb信号, impsar的辐射与接收有其特殊性,即信号的时空偶合,本文定量分析了时空偶合对impsar成像的影响。
It is shown that the spectrum of the backward scattering signal of a rotating target is a slice of the spectrum of the scattering intensity function of the target in the corresponding aspect of the system , weighted by the spectrum of the incident signal 本文简要分析了目标电磁散射与impsar成像有关的信号模型。经对冲激雷达旋转目标某一方向的回波信号的分析,得知它的频谱是目标散射函数频谱在对应方向被发射信号频谱加权了的一个切片。
