【Abstract】 Relevant concepts and theory methods involved in the measurement of radar target characteristics signal-scattering radar cross section (RCS) are introduced in this paper. The paper puts much emphasis on introducing actual engineering project , and the results of theory calculation and measurement data processing are finally presented in the paper.In the aspects of RCS measuring concept and theory analysis, target characteristics data processing methods (including: analysis of theory data, concept and physical property of RCS, calculation of RCS standard value) are introduced emphatically. On the other hand the processing methods of calculation data needed for RCS measurement and radar are also introduced.In the aspects of engineering application, the system project, technological specifications, system construction of the actual RCS target characteristic measuring system are introduced, and system functions and key technology are illuminated.Among them the paper makes it a point to introduce the calculation method and relevant model of radar system which is used to guarantee RCS measuring accuracy, and data-processing subsystem construction, software scheme, requirement analysis with detailed analysis indication and data fusion method, etc.The measuring data and statistics results of scattering cross section (RCS) ( including: RCS-time, RCS-range, RCS-statistics characteristics parameters) are finally presented in the paper.更多还原
