Research On Anti-interference Characteristics Of CART Vector Antenna

Compact Array Radiolocation Technology antenna is one kind of Antenna Array System , which combined with antenna array technique and advanced signal disposal technique , and with fast adaptive capacatiy. On the basis of antenna array, the research on market space speciality of antenna self-structure is an important part for Antenna System. This paper is based on anti-interference features of CART vector antenna , and includes aspects as below:Chapter I, this paper introduces the research background, technical features of electromagnetic vector sensor and Vector Antenna.Chapter II, introduces the basic theory and methods of electromagnetic fields and antenna radicalization relatively which this paper studies.Chapter III, the main content of this paper is to analyze the far-EMF of CART vector antenna , on this basis , composed the electric dipole and magnetic dipole, then analyzed and simulated the far-EMF of antenna array.Chapter IV, based on the detailed research of antenna array, this paper focused on the changes of antenna array pattern and simulate of the ideal under the situation of the different weighting values, to analyze anti-interference feature of antenna array. This paper also studies the antenna polarization and polarization directional pattern , by analyzing the receipt for different signals under the situation of being interfered, to further analyze anti-interference principle of antenna array .Chapter V, finally, this paper gives an introduction of antenna array system, some common antenna array algorithms and computer language based on DSP/FPGA.
