Abstract


Complex calculation of radar cross section has an extremely important role in the area of target stealth and anti-stealth radar identification with anti- identification technology . Accurate estimates for complex target RCS has been an important research topic . Complex target RCS estimates , multiple scattering is one of the issues that must be considered . The occurrence of multiple scattering structure often become the target of strong scattering source for accurate estimate of the RCS has an important influence . This thesis is focused on complex target RCS calculation of multiple scattering problem . First, a brief description of the development of the concept of RCS and RCS computing theory , and basic introduction to the basic principles and methods of computation of GRECO (Graphic Electromagnetic Computing) , after enumerating several commonly used for calculation of the multiple scattering Finally, details a the one for GRECO software multiple scattering calculation . The calculation method is based on the GRECO software for the platform , take full advantage of the characteristics the GRECO visual computing , pixels for basic computing unit search to meet the multiple scattering conditions pixels , the high frequency approximation method in geometrical optics and physical optics combined to achieve complex goals and objectives , multiple scattering RCS calculation . The typical model of the calculation method established by applying the AUTOCAD software comparison validation , the calculation method is proved to have better value in engineering . On this basis of the calculation method by the use of engineering approximation certain optimized , ensuring the accuracy while further improving the operation speed of the program .
