摘　　要：为解决小型化、宽频段、高精度测向问题,采用幅度测向方法,设计了一种基于和差波束的轻便可搬移宽频段测向系统。首先,概述了现有测向体制、适用场景及其典型应用;其次,重点对基于和差波束测向系统的测向误差产生的原因进行分析,并计算推导了误差表达式和仿真比较得出了优化和差波束测向系统测向精度的参数;最后,根据该优化参数,设计了满足实际工程应用的轻便可搬移宽频段测向系统。To solve the problems of miniaturization,wide-frequency-band and high-precision direction finding,this paper adopts the amplitude direction finding method to design a wide-frequency-band high-precision sum-and-different beam-based direction finding system.Firstly,the principles and system charac-teristics of the amplitude direction finding method are outlined.Then,the reasons for the direction finding error of the sum-and-different beam direction finding system are analyzed.Subsequently,the error expres-sion was calculated and derived,and the optimized parameters for the direction finding accuracy of the sum-and-different beam direction finding were obtained through further simulation and comparison.Finally,based on the optimized parameters,a portable wide-frequency-band direction finding system is design to be adopted to the practical engineering applications.
