Target detection in the presence of multiple subpixel targets in complex backgrounds Conference Paper uri icon

abstract

  • In this paper, the detection of point target in a target rich environment is considered. The standard matched filter may be problematic if the estimate of the background is contaminated by neighboring pixels. A second solution, the Orthogonal Space Projection (OSP) implementation of the Generalized Likelihood Ratio Test may be faulty due to the over- definition of the background with the use of too many endmembers. Throughout this paper, a modified version of the OSP test (MOSP) is developed; the MOSP performs well in a point target detection test.
