介绍了0.22 THz步进频率雷达系统及二维高分辨率Is.R成像方法。该雷达系统的合成带宽为12GHz,可以同时实现近场及远场成像。在近场条件下,该系统在距离向和方位向实现二维高精度成像,通过相位补偿反投影算法,太赫兹Is.R图像的分辨率可以达到厘米量级。研究结果表明,采用同样的太赫兹频率步进雷达系统,基于反投影算法的太赫兹Is.R成像可以实现更高的精度和更精细的分辨率。为了加速成像过程,采用了GPU的加速平台,该方法为进一步开展近场高分辨率雷达成像,特别是太赫兹波段雷达成像提供了研究基础。

A Virtual Private Network (VPN) allows.the provis.oning of private network s.rvices.for an organization over a public network s.ch as.the Internet. In other words.a VPN can trans.orm the characteris.ics.of a public which may be non-s.cure network into thos. of a private s.cure network through us.ng encrypted tunnels. This.work cus.omized a s.andard VPN to a newly one called EEVPN (Effective Extens.ve VPN). It trans.its.a s.all data s.ze in through a web bas.d s.s.em in a reas.nable time without affecting the s.curity level. The propos.d EEVPN is.more effective where it takes.s.all data trans.is.ion time with achieving high level of s.curity. Als., the propos.d EEVPN is.more extens.ve becaus. it is.not built for a s.ecific environment.
