    A conditional boost-phase trajectory estimation method based on ballistic missile (BM) information database and classification is developed to estimate and predict boos-phase BM trajectory. The main uncertain factors to describe BM dynamics equation are reduced to the control law of trajectory pitch angle in boost-phase. After the BM mass at the beginning of estimation, the BM attack angle and the... View full abstract»

  • Distribution-based CFAR detectors in SAR images

    Publication Year: 2006, Page(s):717 - 721
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1087 KB)

    As traditional two-parameter constant false alarm rate (CFAR) target detection algorithms in SAR images ignore target distribution, their performances are not the best or near best. As the resolution of SAR images increases, small targets present more pixels in SAR images. So the target distribution is of much significance. Distribution-based CFAR detection algorithm is presented. We unite the pix... View full abstract»
