Description: Content—based image retrieval method is adopted for searching and recognizing interesting
targets of images in radar scene matching image Database in this paper．Radar image is disturbed by
speckle noise seriously，therefore alternating threshold choosing and area growing algorithms are applied
to segment interesting targets(such as airdrome)．Because the radar reference image covers a large area
and includes lots of targets a new method is proposed by dividing 1arge image into several sub-images
and then feature-extracting these sub-images to determine the position of the interested target in the
large image with the bound of sub-images in the whole image．This method WaS verified feasible in air—
drome target retrieval by experiments．
