| Abstract: | The matching reliability by researching on the contrast of gray scale of real time radar image and the character of matching process is analysed. The fix quantity relation between the contrast of gray scale and Nprod is given, it is proved by a great deal of experimentations that the method based on contrast of gray scale of real time image is an effective way to improve the reliability of scene matching of radar image. |
