| titleOfInvention | SAR image target recognition method |
| abstract | The invention provides a kind of target identification method being applied to SAR image.Technical scheme is: the SAR image establishing target template base utilizing target classification known, extract the histogram feature based on partial gradient ratio of template image and testing image respectively as recognition feature, based on LGRPH characteristic Design similarity assessment criterion, carry out realize target identification by the similarity comparing testing image and template image.The partial gradient rate value calculated in process of the present invention adopts ratio approach, to the multiplicative coherent speckle noise of SAR image and scene contrast change insensitive, effectively maintain the information such as the edge of target, angle point, the strong and weak change of local scattering, the precision of target identification method under severe image-forming condition can be improved. |
