A Survey of TerraSAR-X Imagery Satellite for Passive Defense Measurments

In recent years, Synthetic Aperture Radars (SAR) is taking images at different frequencies and resolutions. In this paper, we tried to present a statistical description of military and strategic places using online TerraSAR-X archive. The South West Asia has witnessed many wars in recent years, so this region was selected as the case study. TerraSAR-X has taken image from most of the military and strategic places, for example, missile and nuclear centrals, cities at war, airports, military airbases, dams, seaports, and many other places. Studying the sequence of imaging can help the related organizations to plan about Passive Defense.
