Abstract


CART vector antenna system antenna array technology and advanced signal processing techniques are combined to form the antenna system with a fast adaptive capacity . From the antenna array starting CART the vector antenna space structure has the space field characteristics is an important part of the CART vector antenna system . The anti-jamming characteristics of the for CART vector antenna mainly include the following aspects : first chapter introduces the research background, the technical characteristics of the electromagnetic vector sensor and vector antenna . Chapter II of this article Institute related to electromagnetic fields and antenna radiation to the basic principles and methods . Chapter 3 , the main content of this article . The far field of each element of the of CART vector antenna , and then based on the basic electric time around part of the antenna array and the basic magnetic time around part of the far field synthesis , analysis and simulation of the far field of the antenna array . The fourth chapter , the focus of this article content. Study and simulation on the basis of detailed study of the spatial electromagnetic field of the antenna array , the antenna array element in the case of weighting the change of the direction of FIG Further analysis of the anti-interference performance of the antenna array ; study the polarization characteristics of the antenna array and pole direction map, through the analysis of the weighting of the antenna array receiving different signal interference , more in-depth study of the anti-interference principle of the antenna array . The fifth chapter describes the basic structure of the antenna system , a common algorithm and DSP / FPGA - based computer language .
