| Abstract | ||
| Active imagery technologies such as SAR systems, have significant capabilities comparing with passive imagery technologies such as electro-optical systems. The capabilities of these imaging systems, enable them to acquire and obtain information that are not accessible in the other methods. On the other side, these information are very important for military forces. Hence, some passive defence activities such as camouflage, concealment and deception (CCD) are necessary to secure information against these types of imagery systems. This paper evaluates the capability of the reflectors as countermeasures against SAR imaging system based on their operational model. The reflectors are capable to produce very large radar cross section (RCS) as compared to their size therefore, they can be used as false targets. According to operational model of SAR imaging systems, these false targets appear in SAR images and they cause disruption in acquiring data by SAR systems. This paper presents different plans for camouflage of targets and deception of SAR imaging systems by use of reflectors. A real SAR data of RADARSAT-1 from the North of Iran is used for simulation. The results show the efficiency and effectiveness of the proposed plans for countermeasure against the SAR imagery systems. | ||
