# POSTFEKO Results

The images below show some results obtained by using different post-processing options available in the script.

`phi0`= 45° and an angular range of 24°. The down-range and cross-range resolutions are 0.0370 m and 0.0356 m, respectively.

The angular smear away from the image origin can be reduced by transforming the polar
data to Cartesian coordinates using bi-linear interpolation. The ISAR image with a polar
to Cartesian transformation for a view angle `phi0` = 45° and angular range of 24° is shown. The
down-range and cross-range resolutions are 0.0382 m and 0.0435 m,
respectively.

The image can be processed further by windowing the RCS data. The next ISAR image is the
result of using a polar to Cartesian transformation and a Hamming window for a view
angle `phi0` = 45° and angular range
of 24°. The down-range and cross-range resolutions are
0.0382 m and 0.0435 m, respectively.

The application macro can be used to change the view angle and the
angular range. The ISAR image below is obtained using a polar to Cartesian
transformation and a Hamming window for a view angle
`phi0` = 37.33° and an angular
range of 38.67°. The down-range and cross-range resolutions are
0.0408 m and 0.0265 m, respectively.
