Two-sided Long Baseline Radargrammetry from Ascending Descending Orbits with Application to Mapping Post-seismic Topography in the West Sichuan Foreland Basin

Journal of Mountain Science 2014年第5期11卷 1298-1307页

作者： CHENG Hai-qin CHEN Qiang LIU Guo-xiang YANG Ying-hui LIU Li-yao department of Remote Sensing and Geoinformation Engineering Southwest Jiaotong University School of Civil Engineering and Architecture East China Jiaotong University

One-sided ascending or descending Synthetic Aperture Radar（SAR） stereoradargrammetry has limited accuracy of topographic mapping due to the short spatial baseline（-100 km） and small intersection angle. In order to improve the performance and reliability of generating digital elevation model（DEM） from spaceborne SAR radargrammetry, an exploration of two-sided stereoradargrammetry from the combination of ascending and descending orbits with geometric configuration of long spatial baseline（-1000 km） was conducted in this study. The slant-range geometry between SAR sensors to the earth surface and the Doppler positioning equations were employed to establish the stereoscopic intersection model. The measurement uncertainty of two-sided radargrammetric elevation was estimated on the basis of radar parallax of homogeneous points between input SAR images. Two stereo-pairs of ALOS/PALSAR（Advanced Land Observing satellite/Phased Array type L-band Synthetic Aperture Radar） acquisitions with the orbital separation almost 1080 km over the west Sichuan foreland basin with rolling topography in southwestern China were employed in the study to obtain the up-to-date terrain data after the 2008 Wenchuan earthquake that hit this area. Thequantitative accuracy assessment of two-sided radargrammetric DEM was performed with reference to field GPS observations. The experimental results show that the elevation accuracy reaches 5.5 m without ground control points（GCPs） used, and the accuracy is further improved to 1.5 m with only one GPS GCP used as the least constraint. The theoretical analysis and testing results demonstrate that the twosided long baseline SAR radargrammetry from the ascending and descending orbits can be a very promising technical alternative for large-area and high accuracy topographic mapping.

The fifth generation(5G) wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized, such as mass connectivity, ultra-reliability,and guaranteed low latency. However, 5G will not meet all requirements of the future in 2030 and beyond, and sixth generation(6G) wireless communication networks are expected to provide global coverage, enhanced spectral/energy/cost efficiency, better intelligence level and security, etc. To meet these requirements, 6G networks will rely on new enabling technologies, i.e., air interface and transmission technologies and novel network architecture, such as waveform design, multiple access, channel coding schemes, multi-antenna technologies, network slicing, cell-free architecture, and cloud/fog/edge computing. Our vision on 6G is that it will have four new paradigm shifts. First, to satisfy the requirement of global coverage, 6G will not be limited to terrestrial communication networks, which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV) communication networks, thus achieving a space-airground-sea integrated communication network. Second, all spectra will be fully explored to further increase data rates and connection density, including the sub-6GHz, millimeter wave(mmWave), terahertz(THz),and optical frequency bands. Third, facing the big datasets generated by the use of extremely heterogeneous networks, diverse communication scenarios, large numbers of antennas, wide bandwidths, and new service requirements, 6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI) and big data technologies. Fourth, network security will have to be strengthened when developing 6G networks. This article provides a comprehensive survey of recent advances and future trends in these four aspects. Clearly, 6G with additional technical requirements beyond those of 5G will enable f

With the technical application and development of GPS, the TEC data, the total electron content of the ionosphere, has been measured routinely and used widely in ionosphere studies or in satellite navigation. Therefore, it is very important to accurately measure, calculate, evaluate and analyze TEC. The differential code bias(DCB), that is an interfrequency bias meaning the difference of instrumental delay between two different frequencies, presents in the satellites and receivers of GPS. The accuracy of calculated ionospheric TEC depends mostly on the accuracy of DCB estimates. The study on the DCB is often limited to single type of error calculation and lack of comprehensively quantitative results and statistical analysis. First, we used hardware error calibration method to get the receiver DCB characteristics. Then, long-term zero baseline observations are carried out. We found that the working environment and working conditions of the receivers had the greatest impact on the receiver DCB. Then, we integrated and comprehensively investigates and calculates the ionosphere TEC and the DCB of the satellites and stations, through the accumulation of a large number of muti-source measured data and the results of ionospheric model. The error will be classified by the generating and influencing sources and statistical analyzed. We summarized the distribution and variation of the characteristics of types of the satellite and the station DCB and verify the accuracy of the reliability of error calculation. We found a better compensation algorithm of ionosphere TEC suitable for GPS observations. We provided the theoretical basis and applicaton support to improve the accuracy of the ionosphere TEC data in China.

控制实验表明,不同物种对每个环境因子变化变量产生的响应也存在着差异。植物往往对营养元素的变化反应最为强烈,尤其是氮素的增加。夏季增温实验表明,木本植物对温度的升高表现出了积极的响应,而地衣、苔藓类植物的丰富度却因增温而降低。物种对增温的响应主要受水分有效性和雪覆盖程度控制。在气候保持湿润的情况下,伴随着夏季温度的升高,许多无脊椎动物种群的数量都有所增加。实验表明,CO_2浓度和紫外线B(UV-B)辐射的增加对植物和动物影响较小,但是,一些微生物和真菌却对紫外线B辐射的增加非常敏感,甚至可能会因此产生一些诱导突变而引起流行传染病的爆发。苔原土壤的加温、CO_2浓度的升高以及矿物质营养的改善一般都会增加微生物的活动。在温带气候中,藻类往往比蓝藻细菌更占优势。冬季结冰-解冻过程的增加会导致冻壳的形成,从而会大大降低许多陆生动物的冬季存活率,改变这些动物群体的动态过程。厚的积雪会使驯鹿等植食性动物很难采食到雪下的草类植物,同时也不利于其逃避食肉动物的追捕。而无雪期的提前到来则可能会加速植物的生长。物种对气候变化的响应最初可能出现在亚种这一水平上:一个具有很高遗传/群系多样性的北极植物或动物物种,演化历史已经使其具有一种适应不同环境条件的能力,这将使它们能够很快适应未来的环境变化。本土知识(IK)、航空照片和卫星图像表明一些物种的分布已经发生了变化:北极植被更加趋向灌木化,而且生长也更加旺盛;北极驯鹿的分布范围最近也发生了变化一些原来在树线以南区域活动的害虫和鸟类也在北极被发现。与此相对应,大多数在北极地区进行繁殖鸟类的数量却都在下降。根据一些模型的预测,随着气候的变暖,苔原带鸟类的数量将会大幅度地下降。据物种-气候响应模型预测,由于受到气候变暖的影响,北极地区现有物种在未来的潜在分布范围都将大大缩小和向北退缩,而一些无脊椎动物和微生物则很可能会迅速向北扩展到北极地区。

像木星和土星这样的冷巨行星对类地行星的形成和宜居性起到了关键作用,因此,对像太阳系这样具有多个冷巨行星的系统的搜寻具有重要意义.Kepler以及TESS (Transiting Exoplanet Survey satellite)太空望远镜成功地通过凌星的方法发现了大量短周期行星,然而这些巡天项目的观测基线不足以发现更长周期的行星.为此,天语计划将部署两台1m望远镜(天语一号和天语二号),用于结合天语和其他计划的数据通过凌星法来发现冷巨行星及其他行星,并最终发现类太阳系.天语一号具有约10平方度的视场以及高速CMOS (complementary metal-oxide-semiconductor)科学相机,将对超过1000万颗恒星每小时进行一次高精度测光采样,并通过天语二号的多波段测光、光谱仪以及高分辨率成像对天语一号发现的候选行星进行确认.天语望远镜将放置于海拔约4000m的中国青海冷湖,是目前中国境内最好观测台址之一.天语对亮于14等星的测光精度为0.1%,对亮于18等星的测光精度优于1%,天语预计在5yr内将在类太阳周期发现超过300颗凌星行星,其中包括约17颗冷巨行星.基于系统轨道共面以及孪生地球发生率为10%的假设,天语预计将发现1-2个类太阳系,并可被未来的地球2.0计划所证实.此外,天语还将通过多种巡天观测模式测量从亚秒到周时标的光变,探测不同时标的时域现象,包括超新星早期光变、稀有变星和双星、潮汐瓦解事件、Be星、彗星活动以及系外小行星等.这些发现不仅将深化我们对宇宙的理解,还将为公众科学和科普提供重要平台.
