These experiments are described  and 3 TSI composites constructed by the datasets of these experiments are introduced. The differences of the original data  composite approach and trend of the 3 TSI composites are shown. The argument of the different trends of the 3 TSI composites is discussed  and a conclusion is gotten that low accuracy  low quality and the relative shortage of the early TSI measurement data are the substantial reasons of the differences among the 3 TSI composites. 2012 TSI Press.   Alternating stress dynamics analysis of harmonic gear flexible wheel (EI CONFERENCE) 会议论文  OAI收割 2012 International Conference on Electrical Insulating Materials and Electrical Engineering, EIMEE 2012, May 25, 2012 - May 27, 2012, Shenyang, Liaoning, China 作者:  Li M. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 This article is the study of alternating stress of flexible wheel in harmonic gear drive system. Firstly  then  Finally  according to elasticity theory to theoretically analyze flexible wheel stress  based on the basic principle of sub-structure modal synthesis method  based on the dynamics simulation  use the software of UG  to analyze the alternating stress simulation results of flexible wheel and compare theoretical results and simulation results to come conclusion. The results show that: altering stress simulation results of flexible wheel are coincident with theoretical simulation results  PATRAN and ADAMS to carry out co-simulation  have a deeper understand the stress change trend in the drive process of flexible wheel  lay a foundation for further carrying out dynamics simulation of harmonic gear drive system.

First  establish an appropriate extrapolation model based on the existing data series  and then fit correlation functions other than existing data by derivative least squares method  finally perform spectrum analysis using extrapolated correlation functions. Numerical simulations and the experimental results show that good results are achieved no matter correlation functions change slow or rapid  and the extrapolation error is not more than 2.3%. 2012 Springer-Verlag Berlin Heidelberg.   REGIONAL TREND ANALSIS OF THE AEROSOL OPTICAL DEPTH COMPARING TO MODIS AND MISR AEROSOL PRODUCTS 会议论文  OAI收割 2012 Ieee International Geoscience and Remote Sensing Symposium, New York Guo, Jing; Gu, Xingfa; Cheng, Tianhai; Xie, Donghai; Chen, Hao 收藏  |  浏览/下载：13/0  |  提交时间：2014/12/07 MODIS  MISR  AOD  trend  linear regression   Design of motion compensation mechanism of satellite remote sensing camera (EI CONFERENCE) 会议论文  OAI收割 International Symposium on Photoelectronic Detection and Imaging 2011: Space Exploration Technologies and Applications, May 24, 2011 - May 26, 2011, Beijing, China Gu S.; Yan Y.; Xu K.; Jin G. 收藏  |  浏览/下载：37/0  |  提交时间：2013/03/25 With the development of aerospace remote sensing technology  the ground resolution of remote sensing camera enhances continuously. Since there is relative motion between camera and ground target when taking pictures  the target image recorded in recording media is moved and blurred. In order to enhance the imaging quality and resolution of the camera  the image motion had to be compensated. In order to abate the effect of image motion to image quality of space camera and improve the resolution of the camera  the compensation method of image motion to space camera is researched. First  the reason of producing drift angle and adjustment principle are analyzed in this paper. This paper introduce the composition and transmission principle of image motion compensation mechanism. Second  the system adopts 80C31 as controller of drift angle  and adopts stepping motor for actuators  and adopts absolute photoelectric encoder as the drift Angle measuring element. Then the control mathematical model of the image motion compensation mechanism are deduced  and it achieve the closed-loop control of the drift angle position. At the last  this paper analyses the transmission precision of the mechanism. Through the experiment  we measured the actual precision of the image motion compensation mechanism  and compared with the theoretical analysis. There are two major contributions in this paper. First  the traditional image motion compensation mechanism is big volume and quality heavy. This has not fit for the development trend of space camera miniaturization and lightweight. But if reduce the volume and quality of mechanism  it will bring adverse effects for the precision and stiffness of mechanism. For this problem  This paper designed a image motion compensation that have some advantages such as small size  light weight at the same time  high precision  stiffness and so on. This image motion compensation can be applicable to the small optics cameras with high resolution. Second  the traditional mechanism control need to corrected  fitting and iterative for the control formula of mechanism. Only in this way  we can get the optimal control mathematical model. This paper has high precision of the control formula derived. It can achieve the high precision control without fitting  It also simplify the difficulty of control mathematical model establishment. This paper designed the range of adjusting of image motion compensation mechanism between -5 +5. Based on choosing-5  -4  -3  -2  -1  0  +1  +2  +3  +4  +4 as the expectation value of the imaginary drift angle  we get ten groups of the fact data in adjusting drift angle measured. The test results show that the precision of the drift angle control system can be achieved in 1. It can meet the system requirements that the precision of the control system is less than 3'  and it can achieve the high-precision image motion compensation. 2011 SPIE.   Development situation and trend of domestic and international aerial mapping camera (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Mechatronic Science, Electric Engineering and Computer, MEC 2011, August 19, 2011 - August 22, 2011, Jilin, China Ming L.

Q. 收藏  |  浏览/下载：11/0  |  提交时间：2013/03/25 In the modern military affairs  especially in the complex field  the acquirement of real-time battlefield information and intelligence is getting more and more important  most of this work is completed by aerial reconnaissance or aerial mapping equipment. Aerial mapping camera  with time-sensitive and flexible features  is playing an increasingly important role in modern warfare. With the development of technology  aerial mapping camera has also gone through several generations  gradually from film-based type to transmission type. The theory and composition of domestic and international typical aerial mapping camera is introduced from the development situation and trend in this paper. Finally  with the domestic research status  the development trend of aerial mapping camera is proposed. 2011 IEEE.
