abstract = "The first China-Brazil Earth Resources Satellite (CBERS-1) was
launched in 1999 and was substituted in 2003 by CBERS-2. CBERS- 1
and CBERS-2 have the same specifications and carry three sensors:
Wide Field Imager (WFI), High Resolution CCD Camera (CCD) and
Infrared Multispectral Scanner (IRMSS). In general, the images may
have a blurred appearance due to the cumulative effects of the
sensor instruments and image motion produced by the satellite
movement. This blurring effect can be described by the Point
Spread Function (PSF) which enables an objective assessment of
spatial resolution through the parameter known as EIFOV (Effective
Instantaneous Field of View). Therefore, this work describes three
approaches to estimate the effective spatial resolution of
CBERS-CCD cameras. The first approach uses artificial target to
estimate the EIFOV in across-track and along-track directions
simultaneously, while the other approaches use natural targets to
estimate the EIFOV in both directions separately.",
