Purpose

 

Objects which are moving in azimuth direction are displayed as unfocused lines in (high resolution) SAR SLC images. This tool allows to detect these moving targets by performing the following steps:

 

•Split in 3 sub-apertures in azimuth direction.

•Conversion of the sub-apertures SLC in PWR (intensity). The 3 sub-apertures correspond to different antenna squint.

•Creation of an RGB composite using the three resulting _pwr

 

Thanks to this, moving targets in azimuth direction are highlighted with a complete color spectrum ranging from Red to Green to Blue along the unfocused line.

Distribute and stable targets are showed with an uniform grey coulor (speckle effect apart).

 

Technical Note
