安装 Gamma 软件步骤
1. 拷贝 Gamma 安装包到 /usr/local 文件夹下，解压软件压缩包
2. 安装 FFTW libraries
1) 在 http://www.fftw.org 下载 FFTW version 2.1.5, 拷贝到 /usr/local/lib
2) 解压安装包 tar -zxvf fftw-2.1.5.tar.gz, 打开该目录 cd fftw-2.1.5
3) ./configure --disable-fortran --enable-type-prefix --enable-shared --enable-float --with-gcc
4) sudo make
5) sudo make install
3. 设置环境变量和路径
1) 用 Ctrl+H 显示 /home 文件夹下的隐藏文件，找到.bashrc 文件
2) 将如下加到.bashrc 文件最后
export GAMMA_HOME=/usr/local/GAMMA_SOFTWARE-yymmdd
export MSP_HOME=$GAMMA_HOME/MSP
export ISP_HOME=$GAMMA_HOME/ISP
export DIFF_HOME=$GAMMA_HOME/DIFF
export DISP_HOME=$GAMMA_HOME/DISP
export LAT_HOME=$GAMMA_HOME/LAT
export IPTA_HOME=$GAMMA_HOME/IPTA
export GEO_HOME=$GAMMA_HOME/GEO
export TOOLS_HOME=$GAMMA_HOME/TOOLS
export PLIS=$GAMMA_HOME/PLIS
#then update the path
export PATH=$PATH:\
$DISP_HOME/bin:$MSP_HOME/bin:$ISP_HOME/bin:$DIFF_HOME/bin:
$LAT_HOME/bin:$IPTA_HOME/bin:\
$TOOLS_HOME/bin:$GEO_HOME/bin:$DIFF_HOME/scripts:$IPTA_HOME/scripts:
$GEO_HOME/scripts:$ISP_HOME/scripts:$LAT_HOME/scripts:$MSP_HOME/scripts
#Shared Library Search Path#
export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$GAMMA_HOME/lib:/usr/local/lib
4. # For there are some cshell scripts we should install csh
sudo apt-get install csh
# Image display program eog
sudo apt-get install eog
sudo apt-get install grace
#安装 C 语言编程环境
sudo apt-get install build-essential python-all-dev
5. 安装 GDAL Library (针对 TerraSAR-X PRI 和 geocoded data)
1) 下载 gdal version 1.5 以上的版本(www.gdal.org 或 download.osgeo.org/gdal/)
2) tar-zxf gdal-*tar.gz
cd gdal-*
sudo ./configure --with-python
