基于Radon变换提出了一种新的图像识别方法，首先构造了二维图像在Radon变换空间的平移和比例 不变量，然后根据变换空间数据的特性，利用奇异值分解得到了旋转不变量并将其用于三类飞机的识别，仿真结果表明该方法具有很好的性能和较高的实用价值。(I nt hisp aper,a n ewi mager ecognitionm ethodb asedo nR adont ransform isp roposed,2一Di magem omentin variant basedo nR adontr ansformi sc onstructed.A ccordingto t hed atain t hetr ansforms pace,Si ngularV alueD ecomposition(SV D)i s proposedh ereto o btainr otationi nvariant.Si mulationr esultsa reg ivent oo btaini nsightin tot hee fficiencieso fferedb yo urm ethod)
