摘要
在介绍多波束比幅测向侦察系统原理的基础上,分别分析了天线、微波、接收机引起的测向误差,论证了现阶段利用96波束比幅测向的侦察系统的测向误差,最后给出了提高测向精度的工程应用方面的建议。
Based on introducing the theory of the multi-beam amplitude-comparison direction finding reconnaissnce system,this paper analyzes the direction finding errors in the system aroused by the antenna device,microwave devices and the receivers,demonstrates the direction finding error of 9 6-beam amplitude-comparison direction finding reconnaissance system at present,finally gives the suggestions on improving the direction finding accuracy in engineering application.
