What is the "Synthetic Aperture Radar (SAR)"

SAR is the radio wave imaging radar which provide with a high resolution images seen by radio wave. The resolution is kept even from the satellite altitude.
Since the radio wave passes through cloud, it makes images behind cloud cover even at night.
Several SAR systems are on European earth observation satellites and on a Canadian satellite. In some science mission, SARs were on Space Shuttles. Japanese satellite, JERS-1 ("Fuyoh" is the nick name taken from flower's name), also carried a SAR system.
You can purchase data from RESTEC at a reasonable price.

What is the merit to use SAR image reconstruction software?

Original data of the SAR is a kind of hologram from which you can not find a desired scene. It is converted into a image through a vast amount of data processing. Though you can purchase either the original data or processed image data of JERS-1 SAR from RESTEC, the price of the processed images are very high for amateurs to afford. But the price of the original data which covers a scene is low. So you can save money by producing images from the original data. The author of the processing software intends young students to be interested in satellite images through "process image data yourself". So the software is uploaded as a freeware. You can use the software freely to produce SAR images from JERS-1 SAR original data.

What is the machine to run the programs

The programs run on Windows, Power Macintosh or UNIX (Solaris 2.4/2.5).

Processing Time

You can produce one scene 22km by 47km in an hour on 233MHz Pentium II Processor.

How to use

Refer to the user's manual sheet.

For specialists

Presently, the software produces only real data type images. Soon new version to produce complex images which can be used repeat pass interferometry will be uploaded.
