Considering the information redundancy and complementary in the two compensation methods, we use data fusion method in airborne UWB SAR motion compensation.
考虑到以上两种方法之间存在信息冗余性与互补性,将数据融合方法引入机载uwb SAR运动补偿。
UWB SAR works usually in low Signal-to-Clutter Ratio (SCR) conditions in order to detect targets hidden in forest or buried in ground.
超宽带合成孔径雷达(UWB SAR)为了探测隐藏在树林中或埋于地下的目标,通常工作在低信杂比的环境中。
Three subjects-UWB radar antenna, UHF/VHF band receiver noise temperature, and the target detection from background, which are main factors in UWB SAR range equation, are studied.
