CONF ON CHARACTERIZATION, PROPAGATION, AND SIMULATION OF INFRARED SCENES
作者: REYNOLDS, WR Keweenaw Research Ctr./Michigan Technological Univ. (United States)
Target detection in clutter depends sensitively on the spatial structure of the latter. In particular, it is the ratio of the target size to the clutter inhomogeneity scale which is of crucial importance. Indeed, look... 详细信息
