Abstract: Determining the high-precision image coordinates of CR in SAR images is the basis of geometric correction, radiometric correction and deformation detection of SAR images. This paper presents a coordinate location method of corner reflector in vehicle-mounted SAR image based on scale space. Through corner reflector location experiment in the simulation data and vehicle-mounted SAR data, the feasibility and stability of the method are verified. Compared with the location result after geometric correction using ground control points, the method satisfies the location accuracy of sub-pixel level and does not need ground control points.

Key words: vehicle-mounted SAR, scale space, corner reflector, coordinate location, sub-pixel level
