# ALOS\_pre\_process\_SLC(1)

ALOS\_pre\_process\_SLC

## NAME

ALOS\_pre\_process\_SLC - ALOS\_pre\_process\_SLC

## SYNOPSIS

**ALOS\_pre\_process\_SLC** *imagefile LEDfile* \[*-radius RE*\] \[*-swap*\] \[*-V*\] \[*-debug*\] \[*-quiet*\]

## DESCRIPTION

This program is part of GMTSAR.

creates data.SLC and writes out parameters (PRM format) to stdout

imagefile       ALOS Level 1.1 complex file (CEOS format): LEDfile         ALOS Level 1.1 LED file (CEOS leaderfile format):
