First we depicted one theoretical model of LCoS device, and then working modes of LCoS used as phase-only SLM were selected and optimized by varied the twist angle of liquid crystals and polarized angle due to parameter space method, two working modes, which are suitable to apply LCoS as phase-only SLM, were found, that is (0°, 0°) and (0°, 52°). Theoretical study also showed that the (0°,52°) could be used as a compound device, it behaved property of intensity modulation if a working point was selected appropriately and it behaved property of phase modulation when another wording point was selected. At the same time, this two working modes were studied detailed by extended Jones matrix method.

A new approach to eliminate the ranges dependence based on angular frequency shifting in space domain was presented, in which, the nonhomogeneity of clutter is removed and the blind area of target detection is reduced due to the fact that the clutter of all the compensated range cells in every channel is moved to the place of the clutter of the desired cell by the different angular frequency shifts being added into spatial data along all Doppler channels for every compensating range cell.
第七章针对非正侧视相控阵机载雷达,由于杂波在距离上呈现出严重的非均匀性,尤其是在近程这种依赖距离的杂波谱呈现的非均匀现象更为严重,使得用于计算自适应权的协方差矩阵不可能直接由距离单元数据统计平均来估计得到,否则STAP处理及其降维技术难以获得理想的杂波抑制性能和目标检测性能,甚至恶化。

The results of UV absorption show that λ max is not sensitive to the electronic effects exerted by the substituent in the coupler moiety. The λ max has a small red-shift when the anilide aromatic ring in the coupler moiety is larger. This indicates that the conjugation effect of the anilide ring with chorosorb is not very significant. It is important to note that a red-shift of 60-130 nm was observed when the coupler component changed from a 2-hydroxy-3-naphthanilide to a 2hydroxy-11H-benzocarbazole-3-naphthanilide coupler. The red-shift may be due to the conjugation resulting from the carbazole ring.
对上述三个系列偶氮染料吸收光谱的研究结果表明,偶合基酰胺芳环共轭环的扩大对偶氮染料在可见光区最大吸收红移作用不是很显著;当偶合基萘环上共轭环扩大了一个咔唑环后,其偶氮染料在可见光区的最大吸收大幅红移,跨入近红外染料行列,这一结果对红外偶氮染料的设计合成具有重要的参照价值。
