基于物联网技术打造智慧档案馆室
信息化是将来管理系统改进的主要方向
虽然电子化档案是重要的发展方向,但是实物档案也是重要的资产,特别是涉及保密内容时,两者同样重要
采用自动识别手段,提高操作效率是发展方向
实现档案在位监管,提高资产保全率是重要方向
减少实物档案的遗失等问题发生
从而避免财产损失,杜绝涉密事件的发生(Informatization is the main direction of the improvement of management system in the future.
Although electronic archives are an important development direction, physical archives are also important assets, especially when it comes to confidentiality.
Using automatic identification method to improve operational efficiency is the direction of development.
It is an important direction to realize the supervision of archives in place and improve the asset preservation rate.
Reduce the loss of physical files and other problems.
So as to avoid property losses and eliminate secret incidents.)

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.)
