With the development of near space aircraft, the detection of near space target has become more and more urgent. Beginning with the infrared peculiarities of hypersonic targets and the background of detection, the problem of wave bands choice of land-based infrared detector for near space hypersonic targets is analyzed in this paper. The simulations of target-background contrast are accomplished for hypersonic targets with the temperature of 1000K, 3000K and 6000K. The result of simulation and analysis shows that the contrasts are high at wave bands of 2.85∼4.15μm and 1∼2.52μm, which are applicable for target detection. The contrast of 1∼2.52μm increases with the raising of target temperature. © 2011 IEEE.

Conventionally the international education circle for computer graphics education insists on that computer graphics is based on graphical standards for displaying graphics. This mainstream point of view entails quite a lot of difficulties in computer graphics education. To resolve these problems, this paper proposes a new method of teaching that the fundamental methodology for realizing 3D graphical displays is done by a combination of computer programming and computer simulation. The discipline connotation of computer graphics is distilled in three aspects of research area, methodology and theory architecture. The position and role of computer graphics is re-established in computer science. We expect the new paradigm could solve the problem in computer graphics education that puzzled the international computer graphics education world for so many years. At the same time, the connotation of computer education and the subject framework of computer science are distilled effectively. © 2012 Springer-Verlag GmbH Berlin Heidelberg.
