The Recognition And Extraction Of Surface To Air Missile Position Targets

In the military intelligence field, Remote sensing image is an important means of information acquisition. Timeliness and practicability of the image are widely used investigation of crimes, damage assessment and target location. The surface to air missile has important research significance as a strategic and tactical target. It becomes the focus of the current research, How to combine the manual visual interpretation with the computer feature recognition. The surface to air missile position research will be studied, which is improved the timeliness and accuracy of information acquisition. It will be better prepared for the information war in high-tech conditions.The surface to air missile position identification and extraction plays an important role, but the extraction directly in significantly high remote sensing images more difficult. In this paper, The surface to air missile position and airports relative deployment relationship, as well as the airport and the position of the target shape, spectral characteristics, research and the establishment of interpreting signs. First, after grayscale conversion and histogram conversion processing of remote sensing images sharply divided and filtering, the target and background, in order to gain the airport and the The surface to air missile position contain pre-selected area, narrow scope of the study; and then combined with prior knowledge, visual interpretation, The surface to air missile position to determine the location of the deployment, the use of Hough transform straight edge information extraction and detection Hough transform, The surface to air missile position extraction; and finally through the demand analysis- conceptual model design- logical design model- physical model design, using SQL Server 2010 relational database, complete the construction of the repository.The surface to air missile position with respect to the substantial recognition of remote sensing images, belong to small targets, satellite remote sensing data series of soldiers, ground resolution under ideal conditions can be up to 3 meters, the follow-star resolution up to 1.5 meters, to meet the basic military targets on the ground and extraction requirements, so this choice of satellite remote sensing images as sharp three data sources were studied.Sharply remote sensing images, researchers obtained through image processing and remote sensing interpretation signs preselected area, narrow scope of the study, the use of Hough transform method to extract target, can greatly improve the efficiency of intelligence agents to obtain information and accuracy, the basic realization of computer and artificial eye depending on the interpretation of a combination of methods to extract the SAM sites targets, establish a repository The surface to air missile position, increasing the target information management and information extraction efficiency.
