The stealth warplane for the microwave radar usually have complicated structures with the coating of wave absorption. On the base of calculation and modeling of the geometrical structure of the warplane in real size, the HF RCS of the air crafts under two different polarizations in different direction have been calculated with the FDTD. The result shows that the above mentioned stealth warplane have the obvious characterstics of frequency resonance, polarization and the relatively large RCS in HF Band 10-30dBm2, which can be used as the theoretical reference for selection of working frequency for sky wave OTH Radar and it also means that the sky wave OTH radar has good capability of anti-stealth targets quantitatively.

对微波雷达具有隐身作用的飞机，其形体较为复杂且表面涂敷有强吸波材料在对一种具有隐身几何外形结构实际尺寸飞机进行计算建模的基础上，文中采用FDTD技术得到了两种极化状态下该飞机无涂敷时不同方向上的短波雷达截面RCS值其结果显示了这种隐身几何外形飞机在短波波段有明显的频率谐振特性、极化特性和较大的RCS10-30dBm2，可为天波超视距雷达在选择工作频率时提供理论参考，并定量地说明天波超视距雷达具有较优的反隐身目标能力

In this theory, we firstly introduce the basic theory of discrete wavelet transform and lifting scheme. Secondly, we adopt a fully pipelining VLSI architecture for lifting-based DWT. Hence, we can operate on higher working frequency. Besides, we merge a QCB-based DWT method to achieve the higher parallelism for JPEG 2000 encoding system. By changing the output timing of the DWT process, the internal tile memory size can be reduced by a factor of 4. Moreover, the architecture can efficiently perform shape-adaptive DWT and solve boundary extension and subsampling problems. Finally, according to the comparison results with other architectures, the efficiency of proposed architecture is proven.

在这篇论文中，首先我们介绍离散小波转换和提升式架构的基本理论，接下来我们改良提升式架构采用全管线化的硬体架构，因此我们可以操作在较高的工作频率，并且我们合并了以四个编码方块为基础的方式来使得JPEG 2000编码系统具有更高的平行度，藉著改变离散小波转换的输出时序，内部的记体体需求可以减少为原本的四分之一，接著此架构也可以有效地支援可适应形状的离散小波转换，同时解决了边界延伸和子取样的问题，最后根据与其他架构比较的结果，来说明所提出之离散小波转换架构的贡献。
