图书管理系统,关键字:Access数据库,VB可视化编程,ADO控件。随着人类社会的发展,人类对知识的需求也不断地增长。在这种形势下,书籍就渐渐地成为人们获取并增长知识的主要途径,而图书馆就自然而然地在人们的生活中占据了一定的位置。
学校作为教书育人的中坚力量,图书馆的作用更是举足轻重。学校图书馆要做到安全顺畅的运转,为广大同学提供良好的服务,就必须有一套完善健全的运行管理机制。联系实际,考虑各层次学校的情况,软件本身要求易学,界面友好,容易掌握,可以较简单方便的管理各种图书信息;硬件的配置要求不能太高,这样可以很好的适应当前的学校图书馆。系统的总体特点应该是方便、简单、实用。
本系统主要实现的功能有:图书的编目,图书资料的查询删除以及修改,用户资料的查询修改以及删除,图书的借阅,图书的归还,添加管理员帐户,修改管理员密码等功能。(aaaaa)

SARReturnWaveSignal
基于FFT的快速SAR分布目标回波模拟算法.
大面积分布目标的合成孔径雷达(SAR)回波模拟需要大量的运算,文中提出了一种合成孔径雷达回波模拟的快速算法,算法利用时域插值和FFTl’来缩减运算量,对于大面积目标回波模拟时,该算法有很高的效率。文中详细分析sinc函数插值所带来的误差以及补偿方法,并在次基础上提出了一种利用增采样插值方法,该方法以增加少量运算为代价,使得模拟精度的大幅度提高。文中比较了传统方法和基于FFTl’的快速SAR分布目标回波模拟算法的模拟结果,证明了这种快速算法确实行之有效。(The simulation of distributed targets is very important to the design of synthetic aperture radar(SAR)sys-
tems.Since the end product is SAR images,the echo of SAR signals needs to be simulated and then processed form SAR images,an d the parameters needs to be measured and the perform ance of the images should be,an d then evaluated.The designing parameters of SAR could be adjusted to meet the requirement of users before developing SAR systems,specially
in space—bome SAR systems.Th e simulation data is also needed during the developing an d debugging of a space—borne SAR real—time processor.Another purpose of simulation is to supply a great deal of simulation imag es to train image usors of space—bo rne SAR before it launch.)
