TRAJECTORY BASED 3D FRAGMENT TRACKING IN HYPERVELOCITY IMPACT EXPERIMENTS
Hypervelocity impact Space debris Fragmentation Particle tracking Trajectory fitting Stereo matching
2018/3/30
Collisions between space debris and satellites in Earth’s orbits are not only catastrophic to the satellite, but also create thousands of new fragments, exacerbating the space debris problem. One chal...
Eccentricity in Images of Circular and Spherical Targets and its Impact to 3D Object Reconstruction
Spherical target circular target sphere eccentricity spatial intersection simulation
2014/6/30
This paper discusses a feature of projective geometry which causes eccentricity in the image measurement of circular and spherical targets. While it is commonly known that flat circular targets can ha...
Impact of ADC Bandwidth and Clipping Ratio on COF-PON Systems Based on Spatial Coding and Subcarrier Multiplexing
Analog-to-digital convertor (ADC) clipping ratio code-division-multiplexing (CDM) passive optical networks (PON) subcarrier multiplexing
2011/12/2
In this paper, we analyze the impact of analog-to digital convertor (ADC) bandwidth and clipping ratio on the performance of a 1 Gb/s x 15 user CDM-over-fiber-PON (COF PON) system based on 16-QAM modu...
