  3. Abstract:
  4. The state-of-art technologies keep generating new ways of improving on remote sensing and Earth monitoring like Synthetic Aperture Radars that is widely used in military applications such as reconnaissance and espionage especially on military and industrial sensitive and strategic areas. In order to protection of strategic fields and being aware of hostile activities and also do sufficient countermeasure action, in this research a simple SAR satellite detection and tracking is proposed by using a reliable fast search and tracking antenna considering the limitation of radio visibility duration of SAR satellites. The tracking antenna is a DBF phased array antenna with circular polarized patch elements designed and simulated for a typical known SAR satellite (TerraSAR-X). Monopulse tracking method is used to predict the next SAR reception angles. To eliminate time consuming searching step and start tracking process, azimuth and elevation angles are extracted from the satellite Two Line Elements. The antenna design parameters and the whole tracking process are simulated in Ansoft HFSS and MATLAB software, respectively
