Abstract

The use of space-based and airborne SARs to obtain remote sensing information is increasing day by day due to the very high capabilities of this type of system. So that these types of systems are considered as a supplement for electro-optical systems. Many factors, parameters and sub-parameters are involved in SAR imaging, so it will be shown that there are more than forty effective parameters and sub-parameters in SAR imaging. This issue complicates the understanding of SAR performance, therefore, in this paper, while knowing the SAR imaging system in detail, all factors, parameters and sub-parameters effective in SAR images are extracted and for the first time, a comprehensive classification of them is made to be presented. This classification is important because by determining these parameters, the ground is created for their analysis and finally the extraction of coping strategies specific to the SAR system. By presenting the SAR matrix and the scene in this article, it is possible to manage the acquisition of information from the attacker's SAR and implement this management in the form of different defense plans. For example, at the end of the paper, the simulation of the slope effect in SAR imaging will be discussed, and the RCS value of the sloped structure will be extracted as a countermeasure at different incident angles.
