This dissertation analyses problems of profile aliasing and redundance in chirp - subpulse stepped frequency signal , points out that these problems are resulted from different parameters of chirp - subpulse stepped frequency signal 还对chirp子脉冲频率步进信号中距离像的混叠和冗余问题进行了分析,指出这些现象是chirp子脉冲频率步进信号对不同参数的选取引起的。
Jay williams , the second pick of the 2002 nba draft whose career was derailed by a motorcycle accident , worked out for the rockets on wednesday , though no contract offer was made or is immediately expected 尽管男人阿泰盼望着在下赛季重返赛场,但是他说还没有得到来自联盟的赦免.他对在打架中距离很近且受到惊吓的球迷抱歉,但是不后悔去追逐那个向他投掷杯子的那个人
This includes the ability to log on to the domain controller that is closest to the client in the network and the ability to change passwords on any windows 2000 - based domain controller , instead of the primary domain controller 其中包括：登录到网络中距离客户端最近的域控制器的功能，以及在任何基于windows 2000的域控制器而非主域控制器pdc上更改密码的功能。
Color histogram is used widely for retrieving images , and the processing mostly concerns the choice and quantization of color space , the definition of color histogram and the distance of two points in color histogram space 基于颜色直方图的检索方法是使用最为普遍的方法，该过程主要涉及图像颜色空间的选择、颜色空间的量化、颜色直方图定义以及直方图空间中距离的定义等。
Finally we separate the aberration into space invariant and variant component , which are eliminated by first and second - order compensation procedure respectively . then a method to integrate motion compensation in range - doppler ( rd ) imaging algorithm is presented 最后，研究运动补偿与uwbsar中距离多普勒( rd )成像算法相结合的实现方法，其中采用一阶和二阶补偿以分别消除空不变和空变误差的影响。
This dissertation summarizes the method to select parameters of chirp - subpulse stepped frequency signal , presents a method to resolve profile aliasing and redundance in chirp - subpulse stepped frequency signal by the target pick - up algorithm and selecting parameters 文中总结了chirp子脉冲频率步进信号参数选取的方法,提出了采用参数选取和目标抽取相结合的方法来解决chirp子脉冲频率步进信号中距离像的混叠和冗余问题。
In 1998 , zhou , xiong and zhu improved sh algorithm by reducing this complexity to 2n - lg n . in this paper , we make further improvement . the overall complexity of computing distances is reduced to 3n - lg n 2 , which is only half that of sh algorithm 但是距离的计算量相对于其他基本代数或者逻辑操作来说开销比较大,所以如何降低整个算法过程中距离的计算次数成为我们考虑的重点，我们改进的目标就是使得计算距离的复杂度尽可能的小。
4 . the types of of oil & gas are systematicly summarized . there are three basic type : first : lateral migration along layers with medium distance formed self - producing oil reservoir of neogene . second : migration along fault with short distance formed shallow oil reservoir . third : lateral migration along interlayer and unconformity with long distance 4 、系统总结了歧口凹陷油气二次运移的三种基本方式：一是中距离沿层侧向运移形成下第三系原生油藏；二是短距离沿断裂通道运移，形成浅层油藏；三是长距离沿层间或不整合面的侧向运移。
The apoc 2006 consists of four competitions , the long distance , the middle distance , the sprint and a team relay event . also we will stage a trail orienteering competition for a different taste of orienteering skill test . we also plan to apply for the competition as an iof world ranking events such that elite orienteers are able to have a new venue for scoring their ranking result in asia 举办这次apoc 2006比赛，包括长途、中距离，短途及接力等四个比赛，一连串的定向比赛，提供不同的口味之馀，亦可测试各位赛员的定向技能，我们亦计划申请这次赛事，成为iof世界排名赛，使各位定向精英，在亚洲比赛的成绩，能够计算在世界排名之内。
This thesis mainly studies the digital pulse compression technique and analyses the pulse compression performance of lfm signal with high compression ration . it also simply describes the basic theories of sar imaging and signal processing . based on these theories and high performance digital signal processing chip adsp21160 , we successfully design and realize a frequency domain digital pulse compression system on hhpc board with four adsp21160 embedded 本文主要研究了合成孔径雷达成像技术中距离和方位频域数字脉冲压缩技术，着重分析了高压缩比下lfm信号的脉压性能，简述了合成孔径雷达成像的基本原理和信号处理，在此基础上结合高性能数字信号处理芯片adsp21160研制成功了基于hhpc板的二维频域数字脉冲压缩处理系统。
