摘要
首先介绍了相关干涉仪测向原理,以此提出了在广播式自动相关监视(ADS-B)防欺骗系统中圆阵天线的阵元个数、天线孔径的设计方法,并根据ADS-B的信号特性用MATALAB仿真得出了最佳阵列孔径以及阵元个数,最后设计了ADS-B防欺骗系统的实现方案,并在此方案的基础上给出了系统的硬件架构以及测向算法的现场可编程门阵列(FPGA)实现方案。
Firstly,the principle of correlation interferometer direction finding is introduced,and the design methods of array element number and antenna aperture of circular array antenna in auto-matic dependent surveillance-broadcast(ADS-B)anti-spoofing system are proposed.According to the signal characteristics of ADS-B,the optimal array aperture and array element number are ob-tained by MATALAB simulation.Finally,the implementation scheme of ADS-B anti-spoofing sys-tem is designed,and based on this scheme,the hardware architecture of the system and the field programmable gate array(FPGA)implementation scheme of direction finding algorithm are given.
