This method first jitters chirp rate polarity of LFM signal transmitted by the radar in slow-time domain,then does match-filters for the jamming signals hidden in the radar echoes,since jamming is more powerful than radar echo,the next process of limiting will lower the amplitude of jamming greatly,after limiting process,limited echoes are inversely match-filtered,so jamming and real radar echo are all back to the original time domain,then the next normal imaging process can be implemented which will also provide the real radar echo more gain than jamming,so SJR(Signal-to-Jamming Ratio) is further enhanced.

该方法首先在慢时间域捷变雷达发射信号的调频斜率极性，其次在接收脉冲后首先对转发的干扰信号进行匹配、限幅，然后在逆滤波之后正常成像。

Fluorescence emission spectra and UV absorb spectra analysis have been undertaken to test the influence of solvent polarity on the lowest excited singlet state of the tertiary amines. The absorption maxima were red-shafted slightly, and the emission maxima were red-shafted strongly, which showed all of the three compounds were found to be essentiallyππ* in character, which makes for the formation of triplet-exciplex state and the subsequent reactions,?known as photo-reduction and hydrogen-abstraction.

本文借助光谱检测的手段测试了新合成的增感剂的光物理化学性能，利用荧光发射光谱和紫外吸收光谱测试了溶剂极性对叔胺的最低激发单重态的影响，实验结果表明叔胺的紫外最大吸收波长随溶剂极性的增强产生轻微的红移，荧光最大发射波长随溶剂极性的增强产生明显的红移，表明三种叔胺的最低激发单重态具有ππ*跃迁的特性，这对于激态复合物的生成以及其后的光致还原反应和提氢反应的发生都非常有利。
