In order to solve the problems caused by the unideal movement in the flight and other engineering factors which influence the GMTI, the paper presents the method to compensate the interference phase base on calculate the phase centroid of every sub-image.
Introduction Synthetic Aperture Radar (SAR) along the track interferometry(ATI)[1] ground moving target Indication (GMTI) is one of the most commonly used method of SAR-GMTI, whether in military reconnaissance[2] or civil transportation monitoring[3], all plays a very important role.
According to the SAR-ATI research in theoretical aspects, there are many reports in the literature[4-5] at home and abroad, but also put forward a lot of solution, but most of them are built on the basis of simulation data, this paper has a research institute of airborne real data to ground motion target detection processing, in view of the practical application in engineering problems are analyzed in detail, and gives the corresponding solution, and achieved good results, and to the ground moving target had good heavy positioning and speed.
The Influence Of The Engineering Problems The airborne SAR-ATI in practical application and the problems mainly has two, one is antenna assembly problem, the other is a two channel sampling clock incomplete synchronization issues.
according to is not very detailed testing out of the motion target, and the moving target better speed and positioning, and gives the complete according to real fly data detection process, and got the following practical conclusion: Firstly, Do only moving target detection processing SAR-ATI the imaging quality requirements in is not high, as long as two channel imaging parameters agree, still targets will be effective compensation, reduce the imaging quality to reduce data throughput, realizing fast moving target detection is of great help; Secondly,The track up translation difficult to through the inertial derivative according to get, this part of the distance to the registration effect is very small, the static target of interference phase change can through to the scene for zoning estimate clutter interference phase center of mass get, partition is smaller, ground clutter interference phase distribution range is small; Thirdly, distance up on time with offset is mainly composed of engineering

Utilization and Research on Medium-enthalpy and Low-enthalpy Geothermal Energy in WSHP System Zhang Yi 1,2,a, Guo Dongming1,2,b, Liu Da1,2,c 1State Key Laboratory for Geomechanics and Deep Underground Engineering, Beijing ,China 2School of Mechanics, Architecture and Civil Engineering, China University of Mining and Technology(Beijing),China a songshu770209@126.com, bwjgdm1999@163.com, csuperliuda@126.com Keywords: medium-enthalpy and low-enthalpy geothermal energy, WSHP, numerical simulation, aquifer thermal energy storage(ATES), running costs Abstract.Geothermal energy is a stable energy, stored underground and not influenced by the geographical, seasonal weather and the change of day and night.
Taking water resources heat pump (WSHP) engineering in Tianqiao District as an example, medium-enthalpy and low-enthalpy geothermal energy is combined with the technology of aquifer thermal energy storage (ATES), providing cold energy in summer and warm energy in winter for the buildings.
Application of this technology not only solve heating and cooling problem and also save energy and still avoid pollution. 2 Engineering situation 2.1General situation Tianqiao district lies at the confluence of Dongjing Road and Nanwei Road in Xuanwu district in Beijing, total construction area is 36,000m2，the new building is a multilayered brick and concrete structure, 6 floors.

The present mathematical constitutive models are inconvenient for engineering applications.
These properties of SMAs offer great potential as actuators in variety of different applications ranging through aerospace, marine, civil structures, and medical fields.
The one dimensional constitutive models proposed by Tanaka, Liang and Brinson probably are the most popular in engineering applications.

As an important type of underwater tunnels, immersed tube tunnel are widely used in trans-straits passages and other traffic engineering constructions.
Because of the special hydrogeology environment, the seismic performance become a control factor of survey and design stage for immersed tube tunnel engineering.
For engineering design, on the premise of meeting the design requirements of security and stability, a more flexible approach of the foundations should be chosen preferentially.

Introduction Yichang-Wanzhou Railway spanning 377km is major railway engineering across karst area.
The complicated topography, geological structure, engineering geology and karst hydrogeological conditions lead to tough geological problems in this region, among which the karst water damage is most prominent.
During excavation of deep karst tunnel, water (mud) inrush geological hazard poses severe challenge to railway engineering survey, design and construction.
